@Jov Was just checking this out and OOC/SU threads tend to go in the RP Lounge. The IC is what goes in the RP Corner. Which I wouldn't open that up until you at least got 4 of your 5 characters. (You may want to open more roles and be sure the 5 people that are "The 5" are going to pull their weight and stay active. You don't want to lose a main character to inactivity!)
@Turnip You would want to post your SU, though, for any other people that take part to read. They need to know what you look like and all.
