I received word earlier this afternoon that Silvrback may have figured out what the problem was with my RSS feed. (Some subscribers were getting it and some were not.) The problem appears to be that Comcast's spam filters were apparently viewing the emails as spam.
Okay, one more request. If you signed-up for RSS and didn't get this post, please let me know. (Comcast subscriber or otherwise.) You can contact me here.
Thanks for your help and patience.
