Whether enabling either SSO and Uservoice Authentication, it would be useful to give us the chance to provide the URL created by the OAUTH2 SSO Application created on Facebook or Google side which would be linked to the FB / GOOGLE login button on Uservoice widget.

I like Bejeweled, and I LOVE UserVoice! But Bejeweled stays on top whenever I try to UserVoice because Flash sits on top of the page, so unless it is actively told to be in the background it will be up front. I have to scroll all the way down to be able to see UserVoice, I wish this could be fixed!!
