When you reply, SOME links require you to use this site's protocol. For instance, if you reply to me on this, before you hit "post reply", look up at the top where you see the controls for the font. Go over to the right and click on the three dots. You will see a little image of two chain links. Click on that and that's how you post links that won't "just post" on their own. I agree, it's aggravating.
