I think it may be more effective to subscribe to Pericoach on facebook and click like on their posts on your wall. Then the message is shared among all your contacts. I don't use Facebook much but when I see their posts, I always click like resulting in a friend asking me about Pericoach. Unfortunately there are usually only 2 or 3 likes on those posts. Perhaps we should all do that and help spread the message.
