Congratulations Giancarlo!
This new theme is a good example how dotlrn can be very customized. Maybe we could move to get more themes inspired by this work.
Thanks for this post too so I could learn more about how to build new themes for dotlrn. Until now we were adding graphics for portlets using a UI wrote by Rodrigo Proença (see https://openacs.org/forums/message-view?message_id=213757). Your approach is very instructive for us. Now we could move quickly to get our graphics very integrated in a new theme following your approach.
Thanks
