Okay, I'm a little disappointed right now.
When I did the post about Tagging I had originally copied and pasted the urls right into the body of my message. Then I decided to get more daring, and, checking out the little icons at the top of the New Post box, discovered that I could (I guess that is "should have been able to") replace the typed urls by using the "Insert Link" option. So, I did that and trusted that the inserted links would be available in my post, BUT, they are clearly not there. I wonder, wonder why?
