Betsy,
I'm so happy that the problem was so easily fixed! What a rare treat.
I loved reading your sequential posts this morning in my inbox. After I read the first one, I knew what the problem was. Then I saw your second, test posting and thought, "Well she's going to figure this out on her own." And then there was your final happy message. And it turns out that you didn't even need any help from me.
Well done. 
The cool thing about the link tool is that you can highlight just any regular text, and then insert a web address link for it - it doesn't need to state the address directly. Like this! Okay, that was a bit of Friday silliness, but you get the point. And if you want to unlink something, just highlight it and then click on that broken chain icon up above in the text editor.
Hope your weekend is great, and I'll keep fighting the good fight against those spammy forum invaders,
~Addie~
