@hmiron Basing your community on a limited social media server will restrict your audience.

Build a website to manage it.

Post all your content to that site and push it to as many social platforms as you can. Always link back to *your* site.

The site could incorporate the blog and discourse. Use SSO to allow for quick and painless signup as well.

If you pay for any of these bits read the terms and conditions. Be sure *you* own the rights to the content and not the hosting provider.
