I was looking for a plugin/module to allow registered members to invite others to register and track who invited whom.

Found the Joomla "Winged Messenger" extension, which says its integrated with the Community Builder "cbplug_wmpro.zip" (see extensions.joomla.org/extensions/content-sharing/bookmark-a-recommend/7007). However, an attempt to download the extension results in a 404 error. Anyone know if this extension is still out there and being supported? If not, is there another one that can do this?

Kind Regards,
Kevin
