There is still plenty of time left, so grab your best graphic software and make us some nice banners! You don't have to be an artist to make one, it can be serious or funny, sophisticated or clumsy, ugly or beautiful - doesn't matter if you enjoy creating it!
(And don't say you don't have any software on your pc, you can always use the good old paintbrush
)
HINT: Start Menu -> Run -> pbrush.exe
