Via continuum, the Registration form is only activatable on SSC.  SSI and other billers can trigger it on the VIE client, and request it from bots and chat clients (all of which share the VIE protocol)   I understand why priit would do such a thing, player security for one, but in my humble opinion, the larger of the secondary-level billers should be able to activate this too.  For example, SSI is over 30k users, SSN was of significant size, and both should be (or should have been) allowed access to it.  Granted, there is always the way to make it optional via ?setemail, ?setname, ?setage, ?setsex, yada yada, but honestly, would you ever take the time to fill it out?
