The Mustang 428 Cobra Jet Registry Forum is provided as a free service to anyone interested in the 428 Cobra Jet or the registry project. The forum is hosted on the registry web server to provide nice ad-free features at a reasonable cost. Registration is required to participate as a result of some shenanigans perpetrated by guest users; sorry about that. Terms of service and other legalities can be found when you register as a forum user.
Notice that I mentioned that there's a cost associated with the forum and web hosting service. It currently costs about $100 for one year of service on a fast server without pop-up or banner advertising, and so far the cost has been borne by myself and donations from participants. If you find the forum useful please consider a donation to keep it fast and free of advertising. Instructions for donations can be found on the donation info page.
