It's kind of pointless to post there, but if you have nothing better to do (like me) just keep refreshing. Occasionally people post a code and you just have to hope you're the first to claim it. (You'll want your battle.net open at the code redeem page.)
We do not need a thread dedicated to begging for tyrande codes. As you may notice, just about all the posts here consist of asking for a code. It is very unlikely that many people will drop by and desire to create 10 fake accounts to give away these codes. Please no begging of any kind.
