Just a refresher for people who have been around, and maybe new information for people who have joined recently.
Fosstodon is an invite only instance, but any member of our community can invite others to join, and we encourage you to do that!
That being said, if you're inviting people to our community, please don't issue invites with no limits. Also, if we need to ban 6 people in a week and 5 of them were invited by one person, we're going to start asking questions, so use discretion.
