Huh, the upgrade from mastodon 2.6.1 *shamefaced* to 2.9.2 was actually pretty straightforward. Even upgrading ruby didn't give me any headaches this time.
This Mastodon instance is primarily RPG-focused. Like everything in life, however, there aren't always clear-cut lines and things tend to get blurred. Weapon vs. AC (this server) is currently invite-only.
