Listserv

This module utilizes email to subscribe and unsubscribe users from a listserv that is defined by an administrator. It creates two blocks(subscribe and unsubscribe) that gives users the abiltity to enter their email address to subscribe and unsubscribe from a listserv.

The module also allows other modules to use the listserv_listserv_subscription function to subscribe and unsubscribe a user from their modules.

This module differs from modules like mailing_list and subscriptions in the sense that this module does not manage subscriptions, it only acts as an interface for subscribing individuals to a pre-existing mailing list hosted on Listserv.

A custom drush command is also defined. Use 'drush lsvs [email]' to subscribe a user to the listserv. Type 'drush lsvs --help' for more options.

This module has been tested with Listserv 16.0 only.
