Due to various issues with the Gold Auction House, Blizzard has pushed the release date of the RMAH back even further to an unannounced date. Although this is saddening news it is definitely for the best, the gold auction house has had many bugs that have caused users to lose items and gold.
This website in large is built for the RMAH and we do not wish to start commenting on the economy till it has had time to settle. I have a lot of guides and other things I will begin uploading to the website, but the main content will not be uploaded until the RMAH goes live.

In light of the post-launch obstacles we've encountered, we have made the decision to move the launch of the real-money auction house beyond the previously estimated May time frame. As we mentioned in our original announcement, our goal has always been to ensure everyone has the smoothest experience possible when the real-money auction house launches, and we need a bit more time to iron out the existing general stability and gameplay issues before that feature goes live. While we don't have a new launch date to share just yet, we’ll have more information soon.
