I don't know if vBulletin has this, but several tech forums I've been to recently have this great feature where you can click a button and it prepends the thread topic with the [SOLVED]. This is great for threads that have had their answers given, thus when searching, people find it easier to go for the threads that have answers as opposed to strings of posts about how there is no answer I know you can do this by hand, but a button might make this a more oft-used feature.
