synchro.net email address required
To stop robot account creation, a *.synchro.net email address must be provided when registering. If you have a user account on Vertrauen, then you can register using your vert.synchro.net email address, or use the email address of any other Synchronet BBS that has a *.synchro.net host name.
You can change your registered email address (e.g. to a preferred non-synchro.net email address) once you have signed-in.
