Welcome aboard!!
I can't add anything more than what's been already stated, so I hope you enjoy this site, take your time to get familiar with this site's features, go over the FAQ's, upload your collection, familiarize yourself with the lingo (PWE, FS/FT, PC, and such), read the FAQ's, build up your FS/FT and Wanlists, participate in the forums when you can, go over the FAQ's, build up your profile, ask questions (but only after checking the FAQ's), and have fun on this site, we have great people here (for the most part).
Happy trading!
If your response to "Opening Day" is "for what?"... We cannot be friends.
