As you've probably notice, the way the side blocks on this site work has changed...
Blocks will now pop up menu items when you hover over them, meaning less screen space wasted displaying every link you might possibly need..
Of course this will only work in browsers written during the 21st century, so Mozilla/Firefox, Opera and Safari users will probably be fine, people who are still dumb enough to use IE will have issues, but that's their own stupid fault really.
For the geeky you'll be interested to know the changes made to effect this require no javascript, in fact no modifications to the HTML code at all, it's all done with style sheets (as is right and proper for a display issue)
