Don't know if he could see this post. But I'm a newbie, this is the only place I could post. (or it's possible to notify him via other method?)
yesterday I put a bid option on https://ppcexchange.bitparking.com trying to buy some ppcoin, but today I found myself a unregistered user when I was logging in, facing an error like "Username not found".

Hope someone can help me reaching him. Thanks very much!

He just replied me. It turns out that I was using a wrong user name.
