So the interest section is just what the name says it is.  People who have ideas for role plays run it in that section to see how hyped the audience can get.  It's not normally a sign up just if you're interested in something you tell the GM and then they note down your name for later when they are able to put up the actual thread where you can actually/officially sign up there (by submitting your CS sheet)

I hope this makes sense!
