It's against the rules to post any sort of link like that mate.
SR isn't a legal site? I thought the vendors were the ones breaking the law.
IIRC, theymos didn't want to be facilitating the transactions at all. This was decided back when SR allowed much more sinister stuff (cp, credit card numbers, etc) than's on there now.
ETA: Google "Silk Road URL" -- March 5th link is valid.
