Hello, I'm Opencooper. I wanted to let you know that one or more of your recent contributions to Brazilian jiu-jitsu ranking system have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks.
