Even though I am signed in to my Google Account in Chrome I am still seeing
Sign in or register not Welcome as I expected. When I click Sign in I am
forwarded to a page with one text field to enter an email and a check box
to sign in as administrator. There must be something wrong because I think
since I am logged into gmail it should display welcome?
Thanks in advance...
