Notice: Free email services such as yahoo.com, hotmail.com, mail.com, etc. etc. are no longer accepted for purposes of registration for a free account on CO4x4.org. A Premium Membership is required to use one of these addresses on CO4x4 (see followup post below).
We knew this day would eventually come. As CO4x4.org grows larger it unfortunately attracts more and more disruptive users. Therefore, in an effort to improve our ability to remove abusive users, we can no longer allow users to register for free acounts using free email servers.
