Send an automatic email when the update request is approved

[bishesh]

When users who add new scholars provide their email addresses, can we send an automatic email when admin approves their additions ? This will inform them of whether their requests have been accepted or not.
Or if sending an email without their consent is a problem, how about having a checkbox message that is ticked and says "Send me an email when moderators approve my suggestions" which can be unchecked if the want to ?

should be addressed once mail service is setup.
