I am on another Xenforo forum that has a sub-forum for "projects" that has a really cool formatting to it. I am not sure if it's a stock Xenforo thing or a mod, but it's something you should consider implementing here for the Restoration Showcase sub-forum, etc...
This is what it looks like. Latest responded to post gets top double column spot and all others follow below single column. It would be a plus to use here IMHO.
