Digest trouble

I've set up a digest according to the instructions in 3.11
and using the file .../majordomo-1.94.5/Doc/digest.aliases
as a template but:

1) Subscribers who elected to receive in digest form can't
post to the list
2) mkdigest does nothing: no error, no nothing.

Here's my majordomo.aliases file.

brass-band: "|/usr/majordomo/wrapper resend -l brass-band -h

brass-band-outgoing: :include:/usr/majordomo/lists/brass-band,
