logoff using a command button?

[owens_2k]

is there anyway that i could have a commandbutton as a logoff button for my security. i am using the built in user permissions wizard and i have several different usernames and was just wondering if the user could be changed using just one command button? thanx in advance!

reopen?

The only thing I can think of is opening a second instance of the same db and then closing the first one...
