We have a great new series of checks that make it harder for an administrator to lock themselves out of Crowd. Crowd will issue an error message if someone does something that will remove their own administrator privileges.

When removing a group from a user, the text is currently:

Group(s) "x" were not removed for user "x" to prevent lockout from the Crowd console.

There are a couple of other places, with similar text in the error messages

Instead, something like this may be clearer:

Cannot remove user "x" from group(s) "x". Removing this membership would remove your Crowd administration rights.
