I've manged to get the helloworld portlet and myLayout theme installed.
My question is when I click on the helloworld link in the menu I get a full screen portlet. What do I need to do to retain the look and feel so that the hellowork output appears in the portlet window with a menu to the left and a header and footer as per the default page.
Figured this out after re-reading the docs (several times). All to do with *-pages.xml
