I agree with Jay's first sentence. I also agree with the rest, the cartoonish nature rune and fire rune symbol give a certain feeling of happiness that I think will be beneficial to anyone who uses the forum and it would be nice to transfer this to the rest of the post icons. I also believe the moved topic icon should actually be something because right now it is pretty emo. I suggest something along the lines of the RuneScape trolley image; however, that may be difficult to create given it's width.
I disagree with the text under the avatar area being made smaller than everything else (joined. pc, location, rsn, etc). Everything is so nice and big and then you need to zoom in. :S Unless I am more crazy and it was like that all along.
