[rt-devel] When is a row in the User table created?

[Jesse Vincent]

Actually, in recent releases, RT always creates a user object and links
to that from the relevant watcher object. The fact that it didn't do this 
before was somewhat of a normalization violation.  Basically the email address
style watchers are only for watchers without RT accounts. (All requestors 
have non-privileged accounts automatically created)
