If you want to learn how to make world of warcraft gold and silver quickly without cheating , buying , or paying , read on .
This is actually very easy to do , you only need to have a few things .
1) Create a character you will not play .

2) Get the wow character to Ironforge(Good to start HUMAN-No travel) .

3) Go to auction house .

From here just log out this character right next to the auction house . He/she will not leave this place ever.

Log into a main wow account and start playing as normal . Now instead of selling all your items to the vendors, mail them to your other character in the auction house . Good items to send are most cloths (They go for about 40 silver if you set the 'buy now' price to that) , very nice weapons and armor, and blue rarity weapons and armor(My friend got 6 gold for his blue rare sword).

You don't need to log back to your other character instantly and auction all your items , but everytime you get ready to play WoW , log into the auction character and check before you start playing regularly . There is a mailbox nicely located a few feet from the auction place .

You should auction wisely , if you do , you'll be making a nice bit of silver , then that silver turns to a little gold . The key is to find good items and weapons that you can't use . Sometimes it is good to find those now .

You can even take this a step further and make a second character and auction him like the other one . This would mainly be for if your auction didn't go through , buy those items and you won't lose any money and you'll have the items .
Well, I hope you find this useful , as I did and so does my friend(He has made about 18 gold the last time I checked) .
So , Have fun with this !
