First, let me introduce myself here and excuse me about not speaking french.
I want to talk you about a game we have built. It's called Motocross Virtual, and it's free. It rules on a Manager basis, so you select riders for each Motocross GP and depending of the real results, you earn points.
There are around 200 teams since last Friday when we began. Most of them from UK, Spain, Belgium, Netherlands, Australia and USA. We are waiting for french teams!

Also, we are searching for translators for our site. Please if you are interested send your details and fees through our contact form on the site.
Good luck!
