Whenever you are ready to learn about graphics, you know where to go. At the beginning, I too had no idea how to do this stuff until some very kind-hearted Freepers lent me a hand and got me on my way. I love doing this but the first time learning it was a bit of a challenge. On second thoughts - just jump right in! It's so much fun.
Our USAF troops stationed in Athens can tell you about clear blue waters. Years ago, I was lucky enough to scuba dive off of Athens beach. (R&R from Turkey) It was so clear that you could read a book at 15/20 feet. Loved it. It was one of many "perks" I received courtesy of the US military.
