Design skills wanted for AEU86 logo

[banpei]

Made a few adjustments: removed the background gradient of the postings, and made it consistent with some other elements. The theme looks a bit flat now.
I've also changed the backrgound to a dark-grey color now. It really differs per screen how this is perceived: on a standard monitor it looks very dark, but on my mac it looks very nice.

@kjb: I've also fixed the old template. The problem is that I had to install some plugin to do additional logic in this new theme, and that changed some of the conditionals in whether you are allowed to post or not.
