I can't find the downloads for JReviews add-ons
From JReviews Documentation
The add-ons don't have client area downloads. The Everywhere add-on is bundled with JReviews and will show up in the admin screen once you submit your license number. GeoMaps, PaidListings and WidgetFactory add-ons are installed via the remote installer/updater menu in the JReviews administration.
