There exists an add-on that produces a box at the bottom of a thread showing what people are browsing this thread. Apparently it's not optimised performance wise and since apparently nobody in 2 years saw the need of such functionality that is a default feature in free forum software and xenforo 1.2 nowhere to be seen I am now willing to give some $ to somebody who can code a proper add-on for this. If you don't know what I mean, look at this for a thread: http://community.invisionpower.com/topic/369306-licensing-and-multiple-sites/ and this for a forum: http://community.invisionpower.com/forum/305-pre-sales-questions/ Online users must be split in members, guests, and anonymous/invisible users! (very important!) Of course the who's online list in the sidebar must also show the amount of anonymous/invisible users. Just try to copy what IPB does.
