Doen at the bottom of the main screen of the forum, there is a feature that allows you to see what other users are doing. Is there a way to add pages to this? I have a javascript applet on my site that I'd like to know when people are running.

It's quite easy from PHP, but with JavaScript you will have to implement AJAX, which will slightly complicate matters.

Are you saying it's easy to watch PHP code (from PHP) but not Java?

The applet I'm talking about is launched by a link installed in usercp.tmpl.

Would that require AJAX?

Not it it's invoked from PHP. Look at how the ses_update_status() function is implemented in FUDforum's code:

ses_update_status($usr->sid, 'Start my javascript code');

How would I access this function in usercp.tmpl?

How would the PHP code know when the javascript applet terminated, in order to remove the record in the fud_ses table?

I am guessing the fud_ses table probably expects uid to be unique, that the system expects each user can only be doing one thing at a time. This makes my idea a bit more complicated since the java applet runs in the background. The user will continue to do things in FUDforum while the java applet runs.

Put it in the usercp.inc.t.

It won't, unless you implement an AJAX callback.

The function will clear the user's previous action and updates the table with the user's new action.
