I would say for the most part, no, BUT... What would be nice is to give us the ability to close our own posts in say the For Sale forum, like marking the item sold, but then not allowing those posts to be edited after being 'sold'. Another forum I'm on does it that way, and it saves a bit of hassle if the deal goes bad, and the seller removes something, or changes the description after the fact. As far as other sections, I'd have to say leave it as-is.
