Trial of odoo now running at
  http://markup.co.uk:8069/event

website menu field is for individual event page...

No obvious support for a recurring event

Edit this
   /usr/lib/python3/dist-packages/odoo/addons/website_event/views/event_templates.xml
to e.g. change 'Register' to 'Request place(s)'

Hmm.  Message goes to registrant, but not to admin...

Need to find sources...
What would it take to do a priority-to-newcomers queuing system for
7vt MfW?
 1) Database with tables
      a) adult, with id, name, email (key), household (fk), headOfHousehold (bool)
      b) household, with id, num adults, num children
      c) child, with id, name (key1), parent1 (fk), parent2 (fk), household (key2)
      d) meeting, with id, date, start, end
      e) roomUse, with id, event (fk), room, numAvail (int), numHeldBack (int)
      f) request, with id, event (fk), household (fk), numAdults, allOrNone (bool), numChildren, timestamp
      g) booking, with id, request (fk), room (fk), accepted (int), turnedUp (int)
 2) Actions/forms
      a) Register a household
      b) Edit a household
      c) Request a booking
      d) Show requests/bookings (with expected status for requests,
                                 e.g. currently nth of m for room
      e) Cancel a request/booking
      f) Make bookings and notify head of household for all requests,
            including position on waiting list if not accepted w/o
            qualification
      g) Notify new winner(s), new waiting list positions, on cancellation

Doesn't as proposed allow for different categories of children,
i.e. this really only works for meeting room use for All Age, not
breakout rooms yet.

Do we want to require an acknowledgement?

Waiting list are allowed to turn up, possibly be admitted at 10 past
to empty places from heldBack and no-shows.

Priority based on
 1) inverse number of previous attendances
    a) with no-shows counting double?
    b) with some relief depending on how long ago?
 2) time of request

I.e. compute a score based on previous attendance, then sort by that
score, lowest first, and within requests with the same scores, by
request time, fill room(s) from the top down.  If adding a
larger-than-one household won't fit, if no children and not allOrNone,
accept as many adults as possible.  If there's another room, move
remnant if any there, otherwise move to waiting list, along with
everyone thereafter, in order.

No groups including children on waiting list?
