The problem is that I inherited these forums from someone else -- I don't have a clear sense of which plugins should and shouldn't be in there, nor do I see timestamps on them to be able to pick one out of the lineup because it's recently installed. Certainly I haven't taken any actions to recently install a plugin; the only thing I've done is uninstall forumrunner (and delete its folder on the server).

I'm just going to paste the lot and hope someone has insight into one-of-these-things-is-not-like-the-others:
