Single hook location for all user updates?

[johnmont]

There are a multitude of locations where user information gets updated from within vbulletin -- the admin cp, the user cp, subscriptions, user password/email change, etc.

Is there a single hook location which I can plug into which will allow me to "know" and update another database with certain information? Right now, I've got the same plugin copied in numerous locations....

I'd love to find one hook location that covers it all.
