Thanks, AOU. I figured out what the lock icon meant on my first day on Poal so I was aware of it. The source of this article does not have an HTTPS version so I can't submit one with a cert. I realize some people will avoid non-SSL links like the plague, but unfortunately not all sites have certs even today. I suppose I could archive these links, but I really hate what most archive sites do with the content and especially images. I will try to be more cognizant of the lack of HTTPS in the future but I can't really promise I'll always archive it if there is no secure version.
