Well as this link shows both have been hot by the GW legal team.
In my opinion if Chapterhouse were not so stubborn perhaps GW would of never gotten this aggressive against online content - but who can say for sure?
Of course living in Nottingham does have it perks and I can tell you that at least 2 other big names are in their cross hairs but of course that would be telling and dropping friends in the shit.
I can tell you that GW's legal team are no way as passive, anal, or inactive as 99% of gamers would believe - most of the average store bods at Warhammer World HQ know of these sites recreationally.
