Has anyone ever tried adding an event handler to the User Information List of a site collection? Or for that matter, an alert?

I'd try it out, but was just wondering if there were any issues I should be aware of.

  • It was a hypothetical question that I was asked recently, so I have no firm requirements. We have a collaboration environment (WSS only) and some site collections contain sensitive information. The site collection admins were asking if there was a way to be notified when people were given access to the site collection (intentionally or not) by the site owners.
