When registering for the forums, I clicked the Google registration button, which took me to authorize the forums to access my Google account.
Then it brought me back to the forums, and asked for my email address, password, and other info.
What was the Google button for? I’m revoking the access, of course, but it isn’t clear why the forums would ask for access to my email address in my Google account, then ask me for my email address?
I’d recommend removing the button, since it doesn’t appear to do anything.
