We'll create fresh WordPress site with BuddyPress Friends On-Line installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Plugin will display on your Friends page a new tab called Online with a list of currently online friends.
If will also create a widget that will do the same.
Visit CosyDale.com for more information.
Please rate this plugin. I will develop it further, but need some feedback.
