simple and exactly what we needed

I had to look all over for a good solution to our group mailing list. We have been using Google Groups but privacy concerns directed us elsewhere. I considered Mailman but our host does not allow it. Fortunately they do provide a mail server for general use that works well with this plugin. The interface allows for easy adding and updating users. Users in the mailing group are also WordPress Users which at first seemed very unnecessary; but since our group are all part of the same organization it makes great sense and may open the door to getting more attention on the website itself. Thanks for an excellent plugin!
