Our favorite Everquest sites:

Emerald Templars Message Board - Go here to watch the fur fly as the Emerald Templars debate the controversial topics which shake EQ to its very core!
Gameplay Forum - The official EQ message board. Your best chance of getting an Abashi reply is posting and bumping here.
Everlore - One of the best sites. Make this your home page!
Caster's Realm - something for all pure casters, and a little for everyone else. Best source for jewel craft info. Excellent up-to-date news, and currently the best source of information on the Plane of Air
EQ Stratics - tons of information, forums, news.
AllaKhazam's Magical Realm - if you can't find it on EQ Stratics, you can find it here. Matewan Mendicant's favorite site.
EQ Atlas - great site for learning your way around Norrath. Good zone overviews as well. Only lacking on info for the highest level zones (Solusek's Eye, Nagafen's Lair, Lower Guk).
The Concert Hall - an excellent bard site.
The Dojo - Best monk resource on the net. ***Broken Link, Site Down
EQ Cleric - a fine cleric site.
The Ranger's Glade - an excellent ranger site.
Paladins of Norrath Message Board - a great Paladin site.
