Add a Discourse forum to your Patreon patrons, or, allow members of your community to support it through Patreon membership. For more information, read this blog post about Discourse and Patreon. Use this link to create a new Patreon account and get started.
The planned setup charge of $100 is waived during this trial period. After the first month, you pay $1/patron/month (with a $20/month minimum). For this special Patreon offer, all members of your forum must log in with their Patreon accounts and only Patrons reply or post new topics.
