Please see my reply in microsoft.public.access.forms.

Rather than posting the same message to more than one group (multiposting)
please cross-post (send the one message to all groups at once). To
Crosspost, put all of the newsgroups into the Newsgroups field in the
message header. In this way, all responses to your post will be available
together, regardless of what group the responder was in, and the rest of us
won't have to read your post multiple times.
