Take this as user feedback.

I downloaded the app and it asked me for a forced login using Facebook, with no other choices.

I was expecting to at least be able to bypass the login screen, browse the app a little, and login once I have something to contribute to it or do something with it, but I never found the option.

I don't mind creating an account, but I do mind sharing my Facebook profile even if it's as little as the name and email. An additional option to just register using email would be welcome.

I just uninstalled it and moved along.
