I don't think it'll show up in RSS feeds, so this is a little post to say there's a shadow priest guide page been added to the site, you can access it here or via the links across the top of the page under the banner. I'll be pulling together an equivalent holy post sometime soon, but it took a lot of effort to write and edit so don't expect it too soon. If anyone wants to see anything more over and above these on the site, or has more general comments on the content in the guide please leave a comment or email me.
The reason behind this guide is the abysmal state of information I've seen on the interweb about shadow priests, with incorrect, incomplete, cluttered, and out of date information confusing the hell out of people (including me). I've tried to keep the information minimal and to the point and will be endeavouring to keep it up to date, or at least marking it as out of date if I'm being slack.
