Am I being a total nut or ....?

I thought I'd use email to post for once rather than writing on-line,
but the emails that I sent to immunologysupport@yahoogroups
etc do not appear to have come up. It's been about 40 minutes
now so I would have expected them to show in that time. I
clicked on the mail link that showed in the messages
themselves to do so. Am I doing something wrong? Is there
another way to post by email from the digests?

Thank you anyone, Rose
