Personally I would like to have 2-3 different themes to choose from. The old colours were more suitable IMO but the new forum is more clean and comfortable when it comes to reading in it. Although the lack of sigs gives you the feeling that something is missing. I myself can't do anything about the current colourskin/theme but hopefully the admin can look into this. Until then, sit tight because we're in for a bumpy ride during E3.
