2.6 taken from trunk at some point :) Something we don't necessarly recommend (going into production with this) but they are at home :)
some point == between CR1 and CR2
I was wondering how you were able to have a drop shadow for the right and bottom of the content area. I see from the documentation that you can define a style for the content-container and footer. But to do what you did for that, an extra style wrapping just the content area with out the footer called (contentcontainer) was defined.
Nice Clean Styling, and a good example of JBoss Portal in production.
(there should be a listing somewhere of JBoss Portal in production, and labs.jboss.org should be there)
They defined their own layout.
The list you propose can only be maintained by the community, we are not allowed to disclose JBoss Portal customers, and we don't know where it is used if it is not used by a paying customer. Such efforts have started here: http://wiki.jboss.org/wiki/Wiki.jsp?page=PortalSampleSites
So if you are using JBoss Portal, you can add your website here.
