Good to know.

Is either letting coGMs editing first post for each tab or a GM/coGM note thing at the top of each tab a likely feature to be added anytime soon?

Oh, and thought of another semi-crazy idea, [@Mahz]... How about GMs being able to make announcement type posts in their threads? Say if there's something they want all players to note, rather than general chatter.
Perhaps a shiny frame or somesuch?
