I'm assuming it should increment with each Tweet? (Mine doesn't.)
I have entered my account name into the admin panel.
Something I noticed and had to change when setting it up yesterday: leave off the "@" from your account name...I entered mine as "@yenkoclub", and noticed that it was going through as "@@yenkoclub". Probably pretty obvious to most, but it took my typical 2 tries to get it...with that said, my Tweet counter isn't changing either.
