Possible to adapt "currently viewing"?

[backyardvoyeur]

Hi,

I've just installed the JIRC mod, and wondered if it's possible to adapt the code that shows where a user is on the site at the moment, to show who is currently viewing the chat page?

Something that could go into the overall header, which displays "Users currently on chat page: {usernames}" is what I was thinking of. Not a coder myself but can tinker with existing code if the idea is feasible.

Cheers!
