So it was just brought to my attention that I had inadvertently turned off the comment section on my post. I'd been having some spam problems and I thought that I'd taken care of it by selecting "only blog members" can comment. That seems to mean something very different to Blogger than it does to me! So I've now turned the comment section back on, and if anyone knows of a way to prevent robots from posting topic related links to my content section, I'm all ears. I love our conversations, I just don't want anyone coming by without something meaningful to add !!
