[@Altered Tundra] I have my profile set to invisible. Do I show up as 'Online' in the friends list?

Yeah, you do. I think it doesn't matter if one sets themselves as invisible or not, they show up as online when they are and offline -enter amount of time here- when they aren't. I don't know if Mahz made it that way or if it's one of the things he plans on developing further when he gets the time to do so.
