Hey there,
My brother and I (both GMs) have been writing a pretty great WoW Blog for our guild these past couple months, and it's been a blast. My main is a 70 mage, and every couple of weeks I've been writing a post specifically geared towards our guild's mages with mage advice - things like how to number crunch using Theorycraft-O-Matic, how to sheep appropriately, and Dr. Boom spec-testing.
What I would love are some other mage-specific ideas I could blog about. What do you think? What are some other issues that mainly pertain to mages?
Thanks! Also, you should definitly check out the blog. It's been going really well so far, thousands of views a day, and makes for some nice, patch day, down time reading :)
