You've done quite a bit recently, all for the better, especially having Thank You bump the thread.

As everyone else stated the search function is a pain, but it's nice to see you're looking at an alternative.

The only thing I can think of to improve on is possibly adding a re-up request section, where it wouldn't cost 10 credits to request something that has already been shared here. Maybe this could be in the form of a question in the notification that goes out to someone whose post goes to the recycle bin of whether they intend to re-up the post, and if not, would they mind someone else reposting it. Then all people who have thanked that post would receive a notification and request to re-up that file. It could also simply be a separate section with a lower or no credit charge. Just a thought after reading a post in the request section last week where someone payed 12 credits for a reposted file. Just a thought.
