Registration is checked manually; you may want to register at https://www.fmlist.org/ - asking for access to URDS - before starting the setup and hope it's finished until the “Pi” is ready. In case FMLIST shows up in a foreign language, try to change in the upper right corner of the site.

Same for the mailing list at https://groups.io/g/fmlist-scanner
