One mod I'd love to see is a mod that allows members to exclude specific forums from their searches (e.g. via the "New Posts" button). I use the "New Posts" link all the time to find interesting threads and get tired of seeing hot button thread titles on political and religious discussions.
See Quick Links > New Threads/Posts (Subscribed Forums) - set up your subscriptions first and you can do exactly what you want.
Kind of, but not really, its too kludgy. I'm looking for something that allows me to elegantly ignore specific forums rather than having to subscribe to all of the forums I want. The idea would be to make the "New Threads" link more powerful and useful by having it automatically exclude threads from forums that one doesn't want to see. There must be some elegant vBulletin mod that could do this.
The subscribed forums thing is probably the closest there will be (once you set the forums you care about initially it always works).
