A couple of suggestions -
I myself am 50% committed - you can put me on the list, but I'd like to see enough a critical mass of people saying they will do a tile before I actually start.
- Start a "sign up list" in the first post that lists everyone who has suggested they will do a tile and the theme of their tile.
- Change the name of this thread so it's clearer what it is (involving the words community terrain project or some such may help people to check it out).
- Ask @Malo to feature this story on the site
