I'd like a who's online modification that easily adds urls outside of the forum directory to the who's online content.

PhotoPost perhaps? :D

Actually not just Photopost but yes, that too. i run 3 complete areas on my site. the who's online only works or the forums. I'd LOVE it if I could add locations for everywhere site wide.

Actually I'm after the same thing as well. I think we both follow most of the same forums but if something turns up I'll let you know.
