In response to Karen's question: 

No, I'm not receiving notification that anyone has added anything to this thread, or any other Forum threads I am participating in.   (And yes, I have the "notify me when someone replies" box checked.)   I posted another image last night, and so far have more than 25 comments, but still zero e-bots, so the problem continues.

Re:  last time this happened:

Like Lynn, I checked with my e-mail provider (hotmail) when I was getting blocked content, and they said it had to do with third party servers or something, having to do with the way RR was sending e-mail.  However, that problem cleared itself up in a day or so and I didn't have any more trouble with it at all.

Thanks for your help!
