The WoW Armory may be old to some, but I just recently came across this on the World of Warcraft site. It is called the Armory and lets you take a look at your characters details like their weapons, guild, class, specs and even guild roster. You can even mouse over your gear or a friends gear to see what it does or tell him its a piece of crap or check a characters specific build type (what talents they have learned).

This is my main hunter character and his not so great gear, but you can see our official Loot Ninja Guild name, note the lack of hyphons and dots as these are not allowed in the names of any guilds. The guild roster right now is kind of small since it is new and the settings only allows you to show characters above level ten and we have a couple of people that just started.

Check out your character and post them in our forums.
