Do you mean the Amsterdame08 or the Amsterslam08?
The Amsterdame08 ride is completely full. We're (madly!) taking 71 people including the two support car drivers and 7 ride guides!
We'll be glad to have you along on the Amsterslam event though, but suggest you get your friends to get their application forms off asap as I think Matt's limiting the size of the group to 30ish.
