Tiles.ice.org? I have nothing constructive to add except thank you for bringing back this concept. A few years ago I went back to ice.org to find out it had turned int a wasteland and was completely gutted.

Genuinely shocked to see this resurrected, can't wait to get into this again. Chewed up many a friday night during university. =)

Edit: one thing, any plan for a standard login / google account support or the likes? Kind of a shame that you can't register without facebook or twitter.
