Mailing Lists creates a simple interface for creating custom Mailman mailing lists. Through the mailing lists interface, website owners can create new mailing lists in a few seconds. The interface also allows website owners to modify current mailing lists through the Mailman interface.
The Mailman interface allows the mailing list owner to create a custom interface for users to sign up to the address, prefix mail postings, create welcome messages, and even a message when a member leaves the list. More information on Mailman can be found on list.org.
