Well I can be your mentor if you want! Haha. Pretty much everything you'll need to start trading in right there in the Trade Corner - read the rules first, etc, lurk around and study the threads you see there in the shops subforum.
Also, I can shpw you how to log on the Trade Corner's IRC channel, where you can talk & chat with other traders and the Trade Corner Staff.
And don't hesitate to keep in contact with me when you have more questions. My MSN is on my profile if you use it.
