I am going to try to set my web page up like an old BBS I ran in the mid 90's. On feature it had, that I have seen on other sites (including vbforums) is it would show a list of users logged in.

How could I implement this?

My ideas:

When a user logs on, have a boolean field in the DB record for that user turn on.

Problems- what if they use a cookie that doesn't expire... will they alway be "online"


- how do I turn them "offline" if they don't click on a logout button.... or is there a On_ticket_expired_event?


Any ideas?
