I am currently writing my own forum for my site as there seems to be a severe lack of decent Coldfusion Forums out there and I don't have the money to spend of FuseTalk.

I was wondering if anyone had a way I could display who is currently online (user names) and total number of users currently browsing. I thought of entering the information into the db however this never expires especially if they just close their browser rather than logoff.

Can anyone think of another way to do this?

Thanks
