I've got a World of Warcraft group that meets in Roll20 weekly for roleplay events (specifically, we're a cross-faction warlock coven). We've got about a dozen regulars and I've wanted to encourage newcomers and for people to bring their friends, so I've been pretty liberal with the "Join Game" link. Unfortunately my friendliness has had an unintended consequence. Sometime between last week's meeting and last night, someone entered my campaign and used the draw feature to vandalize the board, leaving a bunch of gross and generic hate speech on the map. It was cleaned up easily enough (and before any regular players arrived, thank goodness) but I'm now stuck trying to figure out who did it so I can kick their gross butt and hopefully prevent it from happening again. I don't think it was a regular, but I've got five names on the "player list" who haven't actually logged in at a meeting time, so I can't even narrow it down from that. Is there a way to track who's logged in to your own campaign when? Or to figure out who did what at a given time? I did browse around the wiki but could not find what I was looking for. Thanks for any help and insight!
