I did not modify myself the .LRN portlets, it was done by Luis who may post later more details... Briefly, the work was to edit the adp associated to each specific portlet (for instance for the groups portlet: dotlrn/packages/dotlrn/www/dotlrn-main-portlet.adp) and then define these new graphic layouts (this was done with Dreamweaver and based on HTML tables). We have several versions of these graphics and we may create a guest account from where you can download the pictures... If it is considered useful, we can also add the templates to CVS.
We are also thinking about more flexible solutions: using CSS instead of tables... the best would be to have a UI where the portlets would be modified dinamically (something like the current Customize Portal Layout).
