This module provides an interface through which users can subscribe to mailing lists run by Mailman.
The administer page allows administrators to add or delete lists and program appropriate request addresses to which commands are sent by Drupal via email. Each subscription is assigned a password which is then used by the module to automatically change subscription settings from within the module, without requiring further confirmation by the user.
Other than the original confirmation of subscription by the user, the use of Mailman as a mailing list software is more or less invisible to the enduser as all settings can be changed from within Drupal.
The combination of this module with mailhandler and listhandler modules replicates to a great extent the functionality of Yahoo!Groups or Google Groups.
Further development is active only for the 5.x and 6.x branches. There is only a development snapshot release of the 6.x branch at this point. There are also releases for 4.7 and 4.6 but these will no longer be further developed.
You should probably consider using https://www.drupal.org/project/telephone instead. Eventually, the validation and formatting features of this module will be moved into a new module that extends the telephone module in both D7 and D8.
The Autosave module automatically saves a snapshot of your content type form using AJAX. If the user's browser or machine dies while editing a node; the edits will be presented to the user the next time they return to the node. The user may toggle back and forth between the last saved version and the version with the edits that were lost and select which of these they would like to continue with.
How often a form is autosaved as well as which content types to enable autosave for are admin configurable.
