if tickets were allowed to be transfered then there is no point in putting the pics on them and getting reg numbers. The idea behind these is to stop ticket touts selling on for an inflated price, if it was poss then lots of people would be able to buy a ticket and then "transfer" it to a friend and maybe even make shed loads of cash to boot. Im pretty sure its not allowed, sorry
i think i remember from last year that if you cancelled a ticket then it simply got put back onto the market for resale. Im sure i read a few threads on a diff forum from some very hopeful people but i dont think i heard 1 sucess story
