I see in the description for this plugin that it says "Manage your member lists by interest or anything ya like to better target your messages"
But I'm not seeing a way to sort the users list by demographics, or by the users profile data, etc.
Apparently, that function is not actually built into the plugin. If it's easy to do, maybe we can modify the plugin to display the users profile data and then filter the list so we can assign them to a newsletter group. I would like it so the newsletter plugin will capture any existing profile data, so that if I modify the user profile fields, they will all be displayed.
