trying jing

I am starting to figure out how to use jing but it is a slow process. I have made my first screen capture and it looks like this:

It is a picture of a mudhole at Yellowstone and my plan is to figure out how to record sound to explain what it is. I also have a 15 sec video of a mudhole burbling away and I assume there must be a way to share that with Jing.
At this point, I am going to read the jing welcome guide to learn how to do this stuff since the intuitive way only garnered this simple screen capture.
