Tom Jenkins from icecubewebdesign.co.uk has designed a new skin for the SuperTuxKart homepage. If you have any concerns, don't hesitate to give feedback; the website is still to evolve =)
The blog will also adapt the new design, hopefully soon.
The GUI for 0.7 might as well take inspiration from it, though this isn't decided yet.
Happy wiki surfing! ;)
EDIT: Blog style now updated accordingly :)
