I dunno if this has been posted before, but it's a really good site to tell you your gear, what instances you should focus on, and if any upgrades are avaliable such as gems and enchants and it ranks you in reference to other players. Very nice site, i use it alot, just pick your realm, pop in your toon's name, and click the live check box and search, takes about 24 hours or so to update if you got a new piece of gear.
