I had seen the advertisements that talked about people selling their characters online but had never really thought to much about it because I did not want to go through a lot of hassle putting mine on the market.  Then,  just to see what it was like I checked out how to create sell wow accounts.  It turned out to be a very easy proposition.  They have a form online and all you have to do is fill in the blanks and it is done.  The more information you can provide the better off you will be but it is all things that you will know off the top of your head.
