okay.... when the forum is opened, the session is set. Their session will expire within a given amount of "inactivity", wouldn't it be nice if you could make a 2 row frame and set one of the page in one frame to refresh itself so if a user is just sitting there with the forum, their session won't expire?
I know it has the option of refreshing everyo "*" minutes but that's manually done and I like to be auto.
I think you can write a programme by vb.It can help you finish this work,,this programme can open a explore window and link to the url you want,close this window .repeat again
Take a look in active.asp there you can select the page to reload every x minutes. Don't know exactly how to do this with a page you don't control though. Your frame option might work, if you can get one page to also reload the other when the one page (you control) reloads itself (might need some client side javascript for that).
