Crypto X Change is now live, and we've got Litecoin and Namecoin markets open for you. See more details on our main post here (including 10oz silver bullion prize!):https://bitcointalk.org/index.php?topic=51457.0
Other alt chains are considered and reviewed on an ongoing basis and may be added at future dates. As mentioned previously, we do not "endorse" any specific alt chains, and inclusion of each alt chain at Crypto X Change is subject to periodic review.
As alternate chains are even more wild and crazy than Bitcoin itself, we really appreciate any feedback from you guys.
Note: we've had requests to integrate a live chat, similar to btc-e.com, and this is in the works. Happy Trading!
