Stephan,

I've confirmed my API public/private key works by using a PHP Class (https://gist.github.com/mkraemer/7483878 (I forked it for use with PHP pre 5.4)). I'm able to use getAccountData successfully.

I haven't deposited anything into my account yet, so I'll be happy to supply my public/private key for testing and then later revoke the key.

Please let me know what action to take so I can get the trading working on BTCChina!

Cheers
Cazz0r
