Please edit the Bitmessage entry with the section on Account Registration.
That registration refers to a totally separate (a “gateway” operated by a different entity not associated with Bitmessage. The use of the domain name bitmessage.ch is or can be misleading as well.) Being a a totally different service from the Bitmessage P2P service itself, its operator attempts to provide a convenient service for users coming in via the public internet.
Also kindly note that this “gateway” service is no longer accepting registrations. There is also a “web clone” at http://a-smail.net/ which uses a different set of certificate credentials while somewhat purporting yet pointing to the one at bitmessage.ch
With the evident wisdom and cautionary best practices exemplified by the gurus at Whonix, I did not want to remain silent least any uninformed person unwittingly assumes that the insecure gateway service is part and parcel of the P2P Bitmessage service which it is not.
