The other modules are: + +- mod_invites +- mod_invites_adhoc +- mod_invites_page +- mod_invites_register +- mod_invites_register_web +- mod_register_apps + +For details and a full overview, start with the mod_invites documentation. + +Details +======= + +mod_invites_register_web implements a web-based registration form that +validates invite tokens. It also supports guiding the user through client +download and configuration via mod_register_apps. + +There is no specific configuration for this module (though it uses the +optional `site_name` to override the displayed site name. + +This module depends on mod_invites_page solely for the case where an invalid +invite token is received - it will redirect to mod_invites_page so that an +appropriate error can be served to the user.
