The plugin provides a means of groups blogs together, in order to be able to quickly select and unselect blogs from the Broadcast meta box.
Local groups are local to the user editing the groups.
Global groups are editable only by the super admin but available to all users.
A User & Blog Settings criterion is provided to allow modifications to react for blogs within blog groups.
An import function allows for importing groups from the free (and obsolete) Broadcast Blog Groups plugin.
