When you register for this forum, you will receive an email to confirm that your email address is correct. The forum can also be configured to update you via email about new posts.
Just under 95% of these emails are arriving fine in users’ email inboxes, but a small fraction are not arriving because they are being categorised by overzealous filters as spam.
If you encounter a problem with this, especially if your account activation email does not arrive, just drop a line to Tom.
I hope this problem does not persist as the website gains recognition as a legitimate source of mail.
