Ok so community banners and icons are now working.
What I've put up at the moment are temporary. We need some good ones, especially for the icon as this is what will be seen by others once federated.
We are now taking submissions and suggestions if anyone wants to have a stab at it.
if you're into Gainax I can't recommend Gunbuster enough. It was even directed by Hideaki Anno. In some ways it's like a prototype of Evangelion.
