"name registration" module - where is it!?

I've got a module listed as "name registration" - it takes a first and last name at registration and generates the username from those (first.last)

There's an issue that i get an empty "group" box (collection of fields - though in this case there are none) - not sure how to solve it.

Trying to look it up however i can't seem to find the module page on drupal.org! anyone come across it?

there's one called http://drupal.org/project/auto_username which seems similar but is not the one i'm using.

thanks,

david
