You can write in english if you want because the translation is not very good and i think that everyone is able to understand.
The Cds Thunderdome with Skyrock's stickers are very rare and hard to find, the person who have the largest collection on this website is Southgabber and i haven't seen theses Cd in his collection. I think you should search on Ebay.fr sometimes there are good offers
good luck
Sorry for my English wich is not very good.
