Sorry if some of these have been reposted, but it would seem that some of the guides you have to download, and there are people paranoid about viruses, so here's a post of sites that I use and give to others.
Class Loot(Learning how to gear your class/spec)
Kaliban's Class Loot Lists
Professions(Steps to leveling it)
World of Warcraft | Strategy Guides
Multiple guides
World of Warcraft Pro | Brings Game Experience to You!
Learn your class in depth!
Quick links to prominent class threads - Elitist Jerks
Finding where the servers are!(Not a guide but still helpful for latency)
US realm list by datacenter - WoWWiki - Your guide to the World of Warcraft
Collection of Macros(Not a guide, but still helpful!)
Category:Macros - WoWWiki - Your guide to the World of Warcraft
I hope this helps people! If I find any more guides/sites that are helpful and worth posting I'll update this post.
Enjoy!
