More annoyances/bugs:
-Passwords MUST be entered on user update pages.
User update pages contain the Password fields, and they are both required to fill out that form. As such you need to enter the password for a user even if you leave the field blank.
Is it not standard practice to have the field do nothing if left blank and if the fields are filled then the new password would be entered into the database?
-No 'Cancel' button in either Registration or Update pages
As stated, no cancel button to take you back to where you were.
