@Barbie has done a wonderful job with the new list and you should be able to find what you are looking for there.
Below is the old link guide, which I have left for any who might still want the old outdated info.
Offsite links are limited and taken on case by case basis. If you are starting out, check out the links with + in front of them. They will cover the basics you need to play and have fun. :)
Note: Most of these are user generated guides and resources.
Guides marked with an ~ sometimes don't load due to site issues.
