Please add an optional setting to allow users to update their own email/username without needing Admin rights.
We are getting tired of only an Admin having the ability to manual update a user's email/username.
In thinking about your request, I believe today you are able to do this already. I think there the control you are seeking is under the Template for the user called "Allow Profile Edit". You should be able to find it under TEMPLATE + SETTINGS + PROFILE.
Hopeful it will work for your need.
