This is my first ever gold guide so go easy on me (just joking).
First get any of the leveling guides for either Horde or Alliance.
Then upload them using sendspace (the best upload site with a max of 300mb!)
Get the download link and make a second char on world of warcraft on give them at least 1silver from you main char (for mail sending)
THen logon to the new char once he/she has the 1s and send 5 or more in-game mails to your main (or the char you want the gold for) char and then open them and get the permanent mail attachment. Then go to a major city (if you are selling a Alliance guide I recommend stormwind and the same idea for horde) and yell : I am selling (the Guide Your Trading) with a download link in a message for (Amount of Gold You Want Depending on the Guide and how many there are)g. Then wait for a reply and trade that permanent message with the download link in for the amount of gold.
I HAVE DONE THIS LOADS AND HAVE BEEN DOING IT FOR ABOUT 2 WEEKS NOW. ALTOGETHER I HAVE MADE ABOUT 100G! I know altogether that might not seem like much but this is mainly used for when you dpn't wanna farm gold or no good quests to do. Basically, it's just a backup.
Please tell me what you think
