Hi, Comcast keep rejecting PBS list posts as spam. I have filled in their form to re-enable email delivery a couple of times in the last month. If you're a comcast subscriber you now know about the problem. You can always keep up with posts via the archive: http://www.pacificbulbsociety.org/list.php#Archive One of our members has pestered comcast a lot about this issue. It might help if others did too. -- David Pilling http://www.davidpilling.com/
