I think the problem with many of the older features is that they were pretty much stock vBulletin 'hacks' that you could get on VBPanel.com. They most likely need serious updating since they've been implemented, and that most likely wouldn't go easy due to the amount of modifications done to the original vBulletin system.

I really don't see anyone sitting down and taking the time to update the tons of files in the archive. I vote, too, to have them removed...maybe it will lessen the flow of the wrong types of people coming in here as well.
