[luau] Administrivia: delayed posts

[Vince Hoang]

I just approved a bunch of messages that were caught due to
non-member submissions. (They currently get held instead of
automatically bouncing. Ugh.)

FWIW, you can subscribe from multiple address and set 'nomail' to
all but one of your accounts if you want to have the flexibility
of submitting posts from different addresses and not be bombarded
with duplicate posts.
