Hi,
There is a "vendor | after_register" view which is currently empty.
We could just display a translated message in the first time but I think it would be better to have a nice page layout.
But, even if the view is currently empty, you can override it and put some content (and use a " JText::_('THANK_YOU') " for multilanguage text).
