Scubaman--It's really easy. Click on USE FULL EDITOR. Once you do that, a new screen will pop up. About 3/4 of the way to the right above the post box, click on the icon that looks like a little world. Once you do that, copy and paste your link, hit OK, and then another box will come up, where you insert a description, or just post "link", or something to that effect.
