P.S. did wetsuit play this one, I'm sure it began with UID 5 on the sheet and that seems quite low for it to be another user.
wetsuit's UID is 4. Check the ref link in his signature!
Does he not have 3, 2 & 1 (so he could technically have 5, I guessed it was a genuine user though).
1 would be root and 2 and 3 admin and/or testing. 5 was the first customer to sign up (I'm 178).
