Today's topic is the start of a set of raid-related Addon Spotlights. I'm really hoping that our commenters will provide more addons that they consider vital for raiding, with links and all, and that I can have a look at them so we can do this again next week. Inevitably, you'll have raiding addons I don't use, or maybe ones that I don't even know about. Tell me about them in the comments! And, of course, today's addons could also be really, really handy for PvP!
Anyhow, a while back in late October, Frego of The Wyld Hunt on The Sha'tar (EU-H) sent me an email regarding an addon he thought I should take a look at.
