This is a list of sites I personally recommend, and sites we are allied to or affiliated with.
Warvault is a very nice site. Its best asset being that it lists links to over one hundred other GW forum sites, so if you’re looking for something specific in a site go here.
Warvault Webring Forces of Disorder is a brand-new community dedicated to the darker armies in the 41st Millennium.
Forces of Disorder forums Throne of Blood, a nice looking site dedicated to the dark Legions of Khorn.
Throne of Blood Boot Camp is a really cool, tight knit community of Imperial Guard gamers. I personaly think the smileys there are really awesome.
Boot Camp Tau online is quite a popular Tau site, so if your considering collecting its deffinately worth taking a look.
Tau Online The C'tan Support Group is one of the friendliest all Necron sites arround. It has some of the best tacticians for the force, and displays quite a few incredable models and entire forces. take a look:
The C'tan Support Group Astronomican - a Warhammer 40k (40,000) community, built by the 40k community for the 40k community. Space Marine or Tyranid, Tau or Necron even Slann or Jokaero - all are welcome.
AstronomicanThe Paint Pot - A Warhammer and Warhammer 40K growing community, and a place to display your WIP and completed models from any GW range. A great place for modellers to get tips and advice, from beginners to veteran painters.
The Paint Pot Keep in mind this is a growing list, so check back regularly for more great sites.
