One of the best ways to make gold in World of Warcraft is to obtain valuable items and sell back on the Auction House for a profit. Farming allows you to do this with little to no money up front or professions needed. The guide will display a list of the highest earning farmable materials and will show you the best place to farm that item with the highest drops and respawn rates.
Learned this today: posted a comment, came back later to see if there was any feedback, reloaded the page: the page posted a copy of my comment. That was not what I wanted. I just wanted to check if my comment was posted and if there were some responses. I did not want to post a copy of my comment from 5 hours ago. And, a humble guess, I think the majority of the users are not expecting such behavior either.
