I'm reviewing the 188.8.131.52 build and noticed a few items:
a. Try changing any password under 'Control Panel - Users - Edit' -- the password field doesn't render as a form field.
b. Typo under 'Control Panel - Profile' next to the drop down list -- should read either 'Switch to User Profile' or 'Switch User Profile'
c. Newletter widget is missing
Thanks for all your effort!
