Hi there, this morning I’ve added three linked posts to the blog, all about addons:
Installing Addons 101 – tells you, well, how to install an addon
Useful Addons for Hunters and Others – List the addons I use, what they do, and has links to download them
My UI – publishes a screenshot of my User Interface, showing how I have it set up, and which addons are used to do this. It also provides a link to WOW insiders column about player’s UI screenshots.
