Transfer game ownership to a player
I believe the Moderators can transfer actual game ownership. Just making a player a GM still limits them. I'm nursing a game along where that happened...I can't do anything to any of the characters that the original GM created...can't rename them, delete them, change ownership on them...and that's just one issue I've noticed, there may be others. Far more reliable to actually have someone make that player the new game owner officially, rather than trying to find work-arounds for the various issues.
