You can make more... but I'll only use one for now. When things start to slow down, if there are any open space I'll fill them with second entires to fill the whole thing up. I'm not sure how many people will submit stuff, this is kindof touch and go.
I'll look into Cycling... but I'd rather have everything on one central main screen. If you want me to use a different sprite and portrait than already listed, let me and I'll swap them for the time being.
