Once you have your contacts added to Fonality HUD, you’ll see if they are (or aren’t) available by the talk bubble. All you have to do is click that bubble and start chatting away. One of the great things about chatting with Fonality HUD is that you can use it across different platforms, including Google and Jabber.
The Fonality HUD has a much more professional appearance than personal IM clients like AIM. More importantly, the HUD integreates several methods of communication--phone, IM, voicemail message--into one box that shows everything you need at a glance.
