Ok, I believe this has been posted before, but I thought I could make it better/easier.
Step 1: You look for someone on MarkeeDragon(.)com and tell them you have this INSANE character you don't want anymore because you're:
1. Sick of the character.
2. Don't have time to play much anymore.
3. or you just really like the other person's toon.
Step 2: Make a MD account and post on the thread and leave your AIM. (Making a new AIM is a good idea.)
Step 3: Contact the person VIA AIM and convince them you wanna trade, but only using a Middle-Man because they are trustworthy and that way neither of you will be scammed.
Step 4: Have a buddy make an AIM Screen-name called something to the sort of "MDMidMan2008" and once the person that's "trading" says, "OK let me have the Middle man contact you." Your buddy AIM's the trader saying, "(name here) told me to contact you about a new trade you guys are doing."
Step 5: Have your buddy invite you and the trader to a chat-room and start the trading process.
Step 6: First ask for their account name/password on the account in a Private AIM message. Once you get that, tell them that you're going to make sure that both characters exist. If they do, then tell them to private AIM message you with the email you want on the account. Then have them send the confirmation link to you (the MDMidMan2008.) Then ask for SQA for both and Names on the accounts. Then you can say something like, OK thanks for the accounts and if either of you try to get your accounts back, I will call blizzard, tell them you're trading and have them IP ban you from WoW. Then block their AIM and you and your scamming partner have just gotten your characters.
Step 7: Congratulate yourself by selling the person's account, trading it for a better char, or just DEing everything he owns...
Hope this guide helps
Been trying to explain it to some people but it gets quite confusing.
PS: Your scamming partner just gives you BS info while you do the talking... You use the partner to get the leads and people to trade while you do the talking and settle everything out. Then when the "middle man" leaves, you both start tripping out and start flippin' so that it's more convincing.
GOOD LUCK!!!
