Since I have only been on the site for the past year, I realize that my opinion may not mean much, if anything at all, but I genuinely like this new template, but there are some issues I have with it. I think there's nothing wrong with the links structure on the side, and that the drop down box is adding nothing bar an extra task to search for your desired system.
While I do like the clean, stripped down look of the new site, my studies in HCID are gnawing at me.
Personally I would keep both the console links and recent posts as they are, but obviously fitting with this new design. I like the placement of the navigation bar and search bar, but I would suggest adding a register/sign in section just under the navigation bar.
In my personal opinion, when developing my own pages, I like to make it so the user can login/register and navigate to any part of the website, from any page, to me, that is just a smart design. Taking as many tasks out of the equation as possible makes for happy users and less maintenance. As a developer I also acknowledge that you have a certain sight in mind when developing the site, so at the end of the day, it's really up to you. Anything I say is mute and void if it contrast your grand view. I imagine the usual's will continue to use this site regardless of what adjustments and changes you make.
