User reviews
Registration was very confusing, I had to go through the proces of adding an account several times before it worked. I was hoping that I could use this to bounce the occasional message, but at a minimum of $49 for an yearly subscription, no thanks. Why software companies no longer sell licences instead of trying to force customers into paying for an expensive or monthly subscription is beyond me. Deleting.

It won't let me sign up for an account. The sign up widow keeps refreshing after I enter and confirm a password.
