Quick suggestion to the developers. Do you think you could hook up with Likno.com to see if they would be interested in building a component for your product. I believe they have one for WordPress and Joomla (http://www.likno.com/addins/dhtml-menu-addins.html).

They have a great product and great customer support and having a component on the "add-in" page would probably drive many folks over to check out Concete5 as well.
