You start by adding the cards that you would like to trade to your organize.

After you do that I would recommend making a trade thread and scannign some of your cards in for people to see.

There is no "Protection" per se. I would trade with people with an established reputation as that can be your protection, no one wants to ruin their rep here.

I would look at value of cards when wondering whether or not to accept. It might be a good idea to pick up the Online price guide if you dont have it. You can also use completed e-bay sales for a general idea of cash value for a card.

The best place to start is to decide what you want to collect.
