Hi Ilan,

Yes, this is quite possible to do.

I would generate a special code for the group of users, then give them a URL that includes that parameter.

e.g. http://www.example.com/my_page_here?reg=x12345

Then in your MetaMod recipe, use this:

if ( JRequest::getVar("reg") == "x12345") return XXX;
// replace XXX with the id of the special registration module. This will only be shown to users who include it in the URL.

I would also ensure that the MetaMod is assigned only to the particular landing page, if you have a menu item for that.

Best regards,
Stephen

Yes, it's no problem for the menu item to be invisible. It works perfectly.
