I just installed my jamLink on 1/31/2010. Within the MusicianLink website, on that same date I sent both friend requests and messages to 10 different usernames. I have not received replies to any of the messages nor friend responses.
Which leads me to believe that your email notification system is broken. Can we get a status or update on when this will be fixed? Without such notifications the social networking function of MusicianLink is severely limited.
