Not sure if crowdstack supports post form templates (my time doing work on vb/xen forums we used aftermarket plugins that added support for them), but they would be a great feature to force threads to be posted in a rigid, uniform, clean, and concise manner on certain forum sections (the for sale forums come to mind, additionally the service forums/help forums where the OP sometimes needs the information ripped from them before an answer can be provided).
Rather than allowing freeform text that either can be very jumbled, or very organized on those specific forum sections, force it all to be extremely organized via the use of a form based post template, you plug in the info, hit post, and it generates the thread title and thread body.
