signature or available text in the account description

Hi

I commonly use a tux as avatar, and I like to thank for it, and I usually give a link to it's creator's web page (in the crystal keep site)
So... this is not an urgent need, nor an important one, but if any can do it, I'll appreciate to have a text field that I can optionnaly fill, either as signature in the forum, or in this particular case, in my account profile would be sufficient at first.
(I know Drupal can do it :) even if I usually work with joomla and phpBB ^^ )

Well, that's it... thanks
