I went into my Squeak-dev settings and changed the Mail delivery option 
from disabled to enabled. So it should kick in and I'll start getting 
lots of emails. I already have it that way for the Beginners list, as 
the traffic is low. And instead of turning it off again, I'll figure out 
how to sort stuff by folders. I think that's the same setup as others 
have, so it's now only a question of waiting for the new setting kick in.
