Hi everybody!

I'm not sure if my post should go here but I would appreciate your advice. I decided to use a web service to organize beta stage better and allow users to leave feedback straight from the software. There's plenty of them on the web (UserVoice, BetaEasy, GetSatisfaction etc.) and I don't know if they allow to integrate feedback button into software.

Maybe someone already uses one of them and can advise me something. Any thoughts on the matter appreciated.
