Being able to edit an email address in E-Newsletter

Still have an issue without being able to change or edit email or other member information for E-newsletter plugin. For example currently it appears that you have to enter an entire new member if the email address changes. There are several problems with this main one being being able to track if newsletter was sent and opened etc... I had requested this a very long time ago and still have the same problems.

Members of various groups end up changing emails more often than I thought. So this is something that I still feel is very important to have completed sooner than later.
