Hal9000 suggested this. It's a simple modification to detect users with more than one login. As each new login is detected a PM will be sent to all administrators with information on the multiple identity users.
Update: Cookie uses configured expiration time and does not expire in 24 hours. Also, there is no on the number of identities tracked per user. As each new identity is used it is reported.
File's attached.
Happy Hunting. It's open season.
UPDATED: 4-15-03 by JoshPet - Added a step to expire the cookies for Admins. Otherwise, even though the cookie isn't set if you are an Admin, you get one when you use the "become this user feature". So as soon as you become 2 users... you start getting "Multiple Identity Detected" PMs out the ying yang. This update will prevent that.

Hope JustDave doesn't mind me updating his code.
