I edit some user accounts. I have some hidden fields that require being filled out for some user types that aren't filled out in registration. In addition, I'll also find an occasional bug where a user is supposed to agree to our terms of use (I have a checkbox field) and amember keeps telling me that it needs to be checked. Checking and unchecking doesn't work. Bottom line - if I'm logged in as admin I should be able to save any edits I want to a user account without having to worry about filling in required fields.
