CrossChoke.com is a free event listing service for the martial arts community.
This site is meant to fill the void left by the demise of icompete.org, a cool site which I had come to depend on for info about upcoming tournaments, seminars and so on. As you probably know icompete.org was down for weeks in early 2009 until eventually the domain was revived by the good folks at The Fightworks podcast.
Something I really miss about the old icompete.org is the ability to search by state, so I decided to use the google maps API to provide users a map-based view of upcoming martial arts events.
