  2. Go to the "Settings" section.
  3. Click on the "Email" tab.

  5. Fill in the required fields such as SMTP address, port number, username, and password. This information will vary depending on your email provider.
  6. Choose the email template that will be sent to the users. Discourse provides a default template, but you can modify it to fit your needs.

How to configure the domain name for the Discourse forum?

To configure the domain name for a Discourse forum, you need to follow these steps:

  1. Purchase a domain name: Choose a domain registrar, such as GoDaddy, Namecheap, or Google Domains, and purchase a domain name of your choice.
  2. Domain provider configuration: Log in to your domain registrar's website and access the DNS (Domain Name System) settings for your domain.
  3. DNS settings: Add a new DNS record for your domain. This record should be a type of CNAME (Canonical Name) or A (Address) record. You will need to point this record to the domain provided by your Discourse hosting provider. This information should be available in your hosting provider's documentation or account settings.
  4. Wait for DNS propagation: It may take some time for the DNS changes to propagate across the internet. This can usually take a few minutes to a few hours, but it can occasionally take longer. After the DNS propagation is complete, your domain will be correctly configured.
  5. Discourse site settings: Log in to your Discourse admin dashboard. Go to the "Settings" section and select the "General" category. Look for the "official domain" setting and enter your domain name there. Save the changes.
  6. SSL certificate (optional): If you want to enable SSL on your forum for secure communication (recommended), Discourse provides a built-in integration with Let's Encrypt. In the admin dashboard, go to the "Settings" section, select the "Security" category, and follow the instructions to enable Let's Encrypt SSL for your domain.
  7. Test and finalize: Visit your forum using the new domain name to ensure everything is working correctly. Test creating topics, posting replies, and navigating the forum to verify that all functionality is functioning as expected.

Note: The exact steps may vary depending on your hosting provider and domain registrar. Therefore, consult the documentation or support of your specific provider if you encounter any issues.

What is Let's Encrypt and how to use it for SSL?

Let's Encrypt is a non-profit certificate authority that provides free SSL (Secure Sockets Layer) certificates for enabling secure HTTPS connections on websites. It was launched to make HTTPS more accessible to website owners by automating and simplifying the process of obtaining and renewing SSL certificates.

To use Let's Encrypt for SSL, you can follow these steps:

  1. Make sure you have root access to your server or have the ability to modify DNS records.
  2. Install the Certbot client, which is the recommended tool for obtaining and managing Let's Encrypt certificates. Certbot is available for various operating systems and web servers. You can find installation instructions on the Certbot website.
  3. Once Certbot is installed, run the following command to obtain and install a certificate for your domain: sudo certbot certonly --webroot -w /path/to/your/website -d your-domain.com Replace "/path/to/your/website" with the actual path to the root directory of your website and "your-domain.com" with your domain name. This command tells Certbot to use webroot authentication and verifies that you own the domain by placing a file in the specified webroot.
  4. Certbot will automatically communicate with the Let's Encrypt server, generate a certificate, and place it in a designated directory on your server.
  5. Update your web server configuration to use the newly obtained SSL certificate. The exact steps depend on your web server software (e.g., Apache, Nginx). You will need to specify the path to the SSL certificate, private key, and any intermediate certificate files in your web server configuration.
  6. Test your SSL configuration to ensure everything is set up correctly. You can use online SSL testing tools to verify your SSL installation.
  7. Set up automated certificate renewal. Let's Encrypt certificates have a short validity period (usually 90 days), so it's important to renew them regularly. Certbot offers automated renewal mechanisms to simplify this process. You can set up a cron job to automatically renew certificates before they expire.

It's worth noting that the exact procedure may vary depending on your server setup, so it's advisable to consult Let's Encrypt documentation or the documentation for your specific web server for more detailed instructions.

What are the system requirements for running Discourse on Vultr?

Discourse is a robust and feature-rich forum platform. To run Discourse on Vultr, you need to meet the following system requirements:

  1. CPU: At least 2 virtual CPU cores
  2. RAM: Minimum 4GB (However, 8GB or more is recommended for better performance)
  3. Storage: At least 10GB SSD storage
  4. Operating System: Ubuntu 20.04 LTS or later version
  5. Bandwidth: Sufficient bandwidth to handle the expected traffic on your forum
  6. IPv6: Vultr provides IPv6 support. Enabling IPv6 is strongly recommended.
  7. Domain Name: A registered domain name that you can point to your Vultr server's IP address.

Additionally, it is recommended to enable a swap file with a size of at least 2GB to ensure optimal performance.

Keep in mind that Discourse is a resource-intensive application, especially if you expect high traffic or have a large number of active users. Therefore, it is advisable to scale up your server resources accordingly or consider opting for a higher-tier Vultr plan.

What are the different user trust levels in Discourse?

In Discourse, there are five different user trust levels, each indicating a certain level of trust and engagement within the community. These trust levels are as follows:

  1. New users (Trust Level 0): This is the starting level for all new users. They have limited capabilities and are encouraged to read, explore, and familiarize themselves with the community.
  2. Basic users (Trust Level 1): Once a user enters the community and spends some time actively participating, they will be promoted to this trust level. They gain additional capabilities such as the ability to post, upload media, and send private messages.
  3. Member users (Trust Level 2): Members are regular contributors to the community who have actively participated over a period of time. They have additional benefits such as the ability to set their own board background and the option to invite others to the community.
  4. Regular users (Trust Level 3): Regular users have shown continued participation and commitment to the community. They gain further privileges like being able to recategorize and rename topics, access to the Lounge category for more relaxed discussions, and more frequent posting limits.
  5. Leader users (Trust Level 4): At the highest trust level, leaders are the most trusted and respected community members. They have almost complete control and management of the community, including the ability to moderate content, handle flags, edit categories, and perform other administrative tasks.

The trust levels in Discourse are designed to encourage user engagement, foster a positive community atmosphere, and gradually reward active and trustworthy participation.
