I setup the help center php application, and it has trouble "staying in sync" with the service.
When I visit the main help center page the list of topics seems to be out of date (sometimes 2 replies when there is 3, etc.)
Each time I log in to access the dashboard, help center has to re "authenticate" with my get satisfaction account, and the API services menu fills up with multiple keys.
I don't like signing up everywhere. GetSatisfaction has done a very good job of reducing the pain (the sign-up at the end, the bare minimum fields, the easy re:captcha). Bravo!
It would be even awesomer, though, if I didn't have to give a password to GetSatisfaction at all... instead, maybe an option to "Sign in using Facebook" or OpenID or Google Account Services or whatever.
