Thanks for the help, Charles!
One problem I have is that I notice that the w3t_key cookie only exists if the user chooses the 'remember me on each visit' option. Is the key stored in the session if the user does not choose to be remembered? And if so, is there a way for me to access it? I guess I don't understand how a user could be logged in with the wrong password, so maybe this really doesn't matter. I just need to be sure they are logged in.
Thanks,
Trav
