I would like to point at some recent improvements to the site, and request feedback which will guide further improvements.
The blocks in the righthand sidebar have been changed somewhat as well. For most of them you can choose whether to display the blocks, or not. There are a few new blocks which are hidden by default, which you can enable. Simply click on 'My Account' in the navigation, then edit your account, and partway down is a section labeled 'Block Configuration'. Click on the blocks you'd like to see (or not see) and away you go. Almost all the blocks are collapsible.
To test a couple more ideas I've created a second theme to the site. It is named 'vmarine2' and you can switch to this theme by, again, going into 'My Account' and editing your account. The main new thing in the vmarine2 theme is a nifty popup menu in the top
Something I haven't (yet) done is reorganizing the navigation menu. It's a little jumbled. What I'd like to do is move many of those entries into this nifty popup menu that's currently in vmarine2.
