Checkout this one www rapidautomator com My group helped develop it. If you have any questions submit them in the forum. It is easy and cheap
I still think Friendstorm is the best. That's just my opinion. Alot of the other ones are either too expensive or have spyware.
The best way is defintively having a good tool to avoid spending nights in front of your computer... I used several friend adder in the past but it was not sufficient. Finally I developped my own and make it multi networks (Myspace, Facebook, YouTube, Last.fm...). You can send add requests, comments and store all important informations of your friends on your PC! Now I can concentrate on music ! François http://www.myspacemarketingmanager.com
