Searched, tested and looked again but I can't find where to add "Use first.lastname for your username please." next to Username cell in the Register page. I know it's not register.php and I'm sure I've looked in every css, php and xyz in the site. Where can I change it please?

Amazing what persistence does, found it in lang/english.php under the registration.php text of course.
Hope this helps others anyway.
