wasnt there always a link or something to see who is online??

No, not really. But you can see how many users are online in your sidebar

ok thanks i always thought there used to be a link that shows you who is online... maybe i got it mixed up with another site

in your User Dashboard there's a Friend Feed, but they'd have to be your Friend.

Like a million years ago there used to be an actual list o the users who were online, but they removed that. :)

thank you... i do remeber that list LOL...
