C3 voice chat communication

just wondering if any1 has heard or tried this program. just google "c3 voice chat" and its the first link to check it out (i dont want to post link cause forum rules).


its a free voice communication that can also connect to facebook to message friends w/o leaving the program.. also has a friends list and chat rooms..


Note: i already know about vent/ts3/xfire/raidcall.. and just wondering if any1 has tried this...;)
