We just switched to the Groupee login and one of my members has this question.

>> I had to retype my email and password rather than use the computer's built-in Autocomplete feature. This Autocomplete is when you double click on an email/password box to log in and it automatically fills in the information. I found it had to be done,"manually", to get it to work!!<<

It works for the password and email using Firefox.
But not with IE. But if you use the google tool bar with IE it will
fill the email portion, but not the password using the auto fill icon.

Hope this helps!
