Hi I am writing a messageboard/forum application and want to include a list of users loged in. What I was wondering was what is the best way to get rid of users that have just gone to another page or disconnected rather than logged out properly.
The users details are stored in an Access Database which contains a field called status (1 for loged in 2 for not).
I guess I could check to see when they last made a request and then have a timeout value of say 20 minutes or so but is there a better way?

Any thoughts appreciated

Alex
