I started working with Mambo, (earlier version), many years ago. Later I continue using Joomla! Drupal and Wordpress, but, this one with more frecuency, for the easiest use, integration, etc.
Now I'll be back on Joomla, thanks to the work of people like this, that is dedicated to developing extensions really easy to use, install, and free for community.
(My spanish compliment).
Thank you very much.
I'll try to keep developing on this level :)
