Thanks for the tip. It helped me find out another set of features, the delimiter field stuff that seem to be effective for better user experience.
However, my main issue is to tackle a 'Terms&Conditions' checkbox in my registration page, with a link to the T&C page. I could get the page hyperlinked into the checkbox title so that worked fine; I just couldn't get the checkbox to be the last field.
Now I did not use delimiter field for two reasons:
-I needed to capture the user's acceptance and I didn't know how to do that with delim field
-delimiter field provides hyperlinking/wrapping in iFrame etc. but I didn't know how to embed a long T&C page inside the registration page conveniently.
I am not a Joomla expert; so I may have missed something else.
