I have been playing around with the Blog design this morning, which is a very dangerous thing to do with my limited knowledge of HTML. I have removed the entire right hand column and moved the links, Podcast Archive etc to the left hand column. I've also widened the central text column.
It seems to all work fine on IE6 and Firefox but I'd be grateful if anyone could alert me to any problems they have. The whole thing should load a lot more quickly and be easier to navigate, if a little less 'pretty'!
