Although I am sadly late to this party, I wanted to tell you welcome to our forum. Hopefully we've been able to answer some of your questions,
Sorry to hear you lost your one thread from getting timed out. The site does have a few tricks of the trade, but I hate it when people have to learn about that one the hard way.
Anyway, you should be able to meet many good people here, and learn quite a bit about poly. Glad you're aboard.
