Hi, my name is John Smith. I caught a link to this site in a google search, and it seems like a very helpful and informative site. A lot of smart people have posted here, and I would like to contribute what I can, and learn what I can. I am in the trade and at times I might be able to answer some technical questions. I am involved in different aspects of the trade. But producing gold, and platinum bridal jewelry is my main focus. Some of you might be able to figure out who I am by my screen name. Anyway, I just wanted to introduce myself, hopefully my post will help some of you.
