Available groups
The following is a list of all available groups:
Adding new groups
To add a new group, you need to create a subpage of Module:Mass notification/groups ending in your group name, e.g. Module:Mass notification/groups/WikiProject Example. You can do this by using the button below. Group names are case-sensitive; {{mass notification|Example}} and {{mass notification|example}} are different groups.
Please make sure there is a consensus to create a group before creating its submodule here, otherwise you risk annoying editors who do not wish to be included. If in doubt, post at the group's talk page (or another suitable talk page if the group doesn't have one) and wait for editors in the group to comment.
If you have any problems when adding a group you can ask for help on Template talk:Mass notification.
