Downloaded it, didn't read the part about the widget so I PMed the developer. Literally in a few seconds I received a respond. For $35 you get this plugin on top of hundreds of others. 10/10 would recommend to everyone.
A true must-have addons for forums that don't have a long "Who's Online" user list. Works as described, and the developer is clearly active and listening to feedback as a suggestion I made was implemented next day. Great work!
Another good one from AndyB. I use this in lieu of XF's default Members Online, since XF still insists on imposing a 60 minute limit on user activity. I firmly believe that users seeing more active members online encourages more activity on the forum, which helps smaller forums grow, and this addon helps accomplish that. The only reason I'm docking it a star is because instead of just showing you the total number of users online and a certain initial number of usernames that you the admin have control over, it shows ALL the usernames, so that you can end up with too many names taking up too much real estate on the side bar.
