Registrarion

[MeetingsandSuch]

Zoom Meetings with Registration - I have a Zoom Meeting setup with registration. The event is recurring over several months, so registration is set so that you register for all occurrences at once.
My speakers need access to only one of the sessions (not all sessions), so I want to give them an individual link and not require registration. So my question... once all those required to register have done so, can I edit the meeting details and turn off registration without screwing up links those who've registered have already received?? TIA!
