Sorry some DNS work made the link unrereachable yesterday. I guess that's why Xenon reminded me that the code must be attached to the first post. The Member.php attached to the first post is what you need, or you can follow the link I provided for an alternative download as it is working again.
As for showing the chat users in "Who's Online" - Chen's hack should do the job nicely:

EDIT: Opps Chen's hack is for version 2. Anyone know of a similar hack for vB 3?
