This module manages the creation and consumption of invite codes for the host(s) it is loaded onto. It currently does not expose any admin/user-facing functionality (though in the future it will probably gain a way to view/manage pending invites).
Other modules can use the API from this module to create invite tokens which can be used to e.g. register accounts or create automatic subscription approvals.
Note that all modules that use this API will automatically load this module, so adding it to modules_enabled is generally not necessary.
0.11 and later.
