So, just had a thought. On wajas.com the threads have a 'bump' button that bumps the thread without having to take up a post for a bump. I was thinking if something like that could be implemented it would probably be quite useful! Thinking in terms of the Trade Board: It would unclutter the threads and so only potentional customer questions/update posts from the seller (who maybe post the update and then also add it to the main post) can be seen. For other things- some people tend to shy away from boards that have a ton of posts when in reality the majority of those threads are probably just bumps.
Either way, I think it would be useful for the trade boards at least, maybe! Thoughts?
