Does anyone know of a plugin that will create a mailing list from all registered users? This would be useful for our club instead of having to keep our mailing list up-to-date among all of our members. Instead members could log in to our WordPress site, click on a link and have their mail client populated with all of the addresses for all people in the club. Sounds simple and it could be done manually, but would be nice if there was a plugin to keep the list up-to-date automatically. Thanks!
