Removing the Title on Registration page.

Its a rather simple question. I hope the answer is as simple.
How do I remove the Title on the Registration page?

The text at the top that says Registration.

thanks in advance.

The page title is adjusted through language strings
in
/components/com_comprofiler/plugin/language/default_language/default_language.php
modify
DEFINE('_REGISTER_TITLE','Registration');
in
DEFINE('_REGISTER_TITLE','');

Hello,

And how can I increase the title size? Or use this title as an <h1> (html tag)?

Many thanks in advance
