It may take a while to get the point, but the lessons are free. Read past forum information or search for a question you have to see what else you can learn. If you question anything else, just ask. When reading the first post, look at the coin and see if you can figure out what is different with the coins images, before you read the entire post. This way you can see if you are correct. Sometimes you may have to wait for the correct answer. It is just like going to school, everything doesn't come at once to you.
