Good plugins?

[MasterZuFu]

My plugin list is massive...between 52-63 plugins total, plus several template edits. I've had to learn to use my default templates so that when I upload new theme I can always use the same templates without losing my template edits.

To answer your question more directly though, the only plugin I'd find questionable would probably be the chat plugin because I've often found chatboxes and shoutboxes to be rather exploitable. I now use blue imp's chatbox (but it has its own page, it's not in the footer of your forum).
