This module implements the {{tl|mass notification}} template. It is used to send notifications to a WikiProject or other group of users.
Usage from wikitext
Usually you should use {{tl|mass notification}} rather than calling this module directly from #invoke. However, if you want you can use the syntax {{#invoke:Mass notification|main|group name}}. See the template documentation for details about group names.
Usage from Lua modules
To use this module from other Lua modules, first load the module.
You can then generate the notification links by using the _main function.
groupName is the group name, as a string, as explained in the template documentation.
