I have been testing the breezingforms component for joomla.
Like most joomla form components, it comes complete with a link to the authors site. I had a quick look in the facileforms.php file located in components/com_facileforms/ and saw that it can be removed by editing line 423.
if(trim($form->template_code_processed) == 'QuickMode') echo '<br/><br/><div align="center"><a href="http://www.crosstec.de" target="_blank">Forms for Joomla!© by Crosstec</a></div>';
and the link is removed.
However, be sure to register if you decide to use the component and get all the support and upgrades available from www.crosstec.de
