Hi, Joseph
It is very kind of you to give me your advices :) I really appreciate that. I have contracted with David Pilger several days before. He just said that some people was trying to do the same stuff that we were going to. Do you know about that? I am a freshman in this area and have little experience. I think it is an good idea to stand on the shoulders of giants and see further. Could you give me the further information ? Thank you.
