Hmm, it was a couple years ago and that site is no longer running.
I edited include/registerform.php to add at line 143:
// Add Real name required
$reg_form->addElement(new XoopsFormText(_US_REALNAME, "name", 26, 25, $myts->htmlSpecialChars($name)), true);
// End Real Name
That file has completely changed in 2.4
I tried similar "name" additions in register.php and modules/profile/register.php and one other I can't remember now (sorry, late night experimenting with no documenting...)
