Well that was my point if you can find a old mod then it would have a clue on what file to edit.
Gizmo made a comment ReCaptcha so that might be it.
Since classic was a declared end of life there are not to many active people here that still use it.
So it is all from memory now.
Maybe Allen can dig something up from the archives he has saved.
BTW there is not a html page. Classic was cgi based. It did have a feature later on to add a html extension to the url.
But anyway a starting point would be ubb_registration.cgi.
