I suggest adding a notification in RP thread creation to warn people about interest checks. Maybe a button that requires toggling to post the thread, or a pop up of sorts? Just so people, usually newbies, stop posting interest checks in the roleplay section. People who are making an invite only RP or whatever with friends or past RP mates can just click and go, but I figured this would sort of clue people into that "hey, maybe you should make an [i]interest check[/i] opposed to a [i]roleplay[/i] thread first".
