Misleading UI and Bad Missing Fields Error

[ruizha]

When I click log out, with all fields filled, even the optional ones, it gives me the pop up notifying me I have missing fields.

There really should be a submit button instead of a "Save Changes", since it is very possibly the case that someone wants to save their changes but not necessarily submit the form. I think it would be a good idea to change the "Log out" to be Submit or something, as there is already a log out in the sidebar.
