Welcome Emerald 9.244 - the inimitable Joomla membership extension!
In this new version we introduce our new innovative feature called RDS. This is abbreviation of Registration During Subscription.
Note! This is not the same as subscription during registration (SDR). When it is SDR, user select Emerald subscription plan on registration form. But with RDS, there is not registration form. User simply pay a subscription without registration.
Amazed? And I am not surprised
