Absolutely.  Of course that can be the human readable version of a
machine friendly numeric primary key.

Ahh, thanks.

Yup.  I'd like to note, and not just to be pedantic but because I really
don't feel that I've thought through it fully, that it feels like
there's a larger set of "partial" states for mailing lists than I

The need is to take a list into a state where it appears to have been
deleted to everyone involved but me as SysAdm/ListMaster, I then keep
the list configuration around as an audit trail, a set of configuration
details (eg headers/footers) to copy from when instantiating a new list,
etc.  This is something I've wanted here and have accomplished under
Mailman v2 by turning off password reminders for the list, disabling the
email aliases, and flagging the list to not be shown on the listinfo

Cool.  Hope I'm not jumping in too hard here Barry.
