Joan,
I don't know exactly how it happened but your profile was actually set to Individual Messages. Since I'm one of the moderators on the list, I just changed it to Digest. It can take up to 48 hours for the change to take effect, but it will probably happen before that (hopefully).

In making changes like that, there is usually a Save button so it may be you didn't see that, or that there was a temporary disconnection right after you pressed it, or something.

But whatever it was, hopefully now you are all set.
