With the phpArmory class library submitted to GitHub.com, I decided to push the WordPress armory plugin into a GIT repository, too.

For now, wow-armory 1.0.0 has been committed and you can see the current library state at the wow-armory GitHub page.
I’ll be committing a few updates soon.
I stumbled across your plugin (github++) and decided to install it on my WoW blog. Is there any documentation anywhere? I’m aware of the [item] links, but can I do the same for a toon, or a spell, for example? If so, what are the tags?
Not yet. For now, you can use Name of the Item to get an item link. The hover tooltips are not working yet, only colouring the link in the correct item quality colour, and adding a link the the armory.
I was working on a rewrite of phpArmory, to make a few additional features available to the plugin. This will be finished by Sunday, then wow-armory will receive its’ update.
