We had a huge problem with people prematurely bumping their classified threads, having their friends sign up to bump threads, etc. Our solution was to use an existing modification which limits bumps by the original poster and disable all replies to the thread, except by the original poster. This means the original poster can reply to their threads all they want, but it will not bump until after the time limit has passed (7 days in our case). This works well, but the members want to be able to post in the classified ads again.
I need either a new add-on which will make it so only replies from the original poster bump the thread, after my specified time period, in a specific section of the site, and allow members to still post in the thread. If it would be easier to code we can even make it so none of the replies bump the thread and the original poster has to click a bump button.
I know this is rather simple, and I need it done as soon as possible.
