Hi everyone, I am Alfred. I found this site months ago, and I learned a lot from this site. I appreciate all your help. I hope I can also share some of my knowledge here. I learned some IM knowledge before, but I cannot get big profit from them. I just don't have time to do all these articles, social mark, backlinks, forums, etc. But these are very useful. Most IMers here know them, but I hope I can help.
