The saga continues: I'm getting the impression that SugarSync doesn't want me to sign up and start using their service.
I clicked on the "Activate your email address" and was taken to the proper page where they requested that I type in my password (set during the sign up process). I did so - several times. Each time there was about a 10-second delay (what's that all about?) and then they rejected it as an "invalid password". Now I know I typed it in correctly because I keep my passwords on 4MyPasswords [Disclosure: this is a site that I built and maintain] so it's not about forgetting my password.
What to do now? Well, they offer to reset your password... and of course they get you the new password by... you guessed it... emailing you a new one!
I wonder how long this email will take...
