I can't recall, but I thought I might add this.
There are plenty of what I consider, 'elite' Imperial Guard blogs (or plogs or klogs or whatever you call them) on Warseer. I don't want to divert w-e traffic to that forum specifically, but I know most of you have been there...
The pattern I've noticed also, was that these 'elites' tend to group to same forums... so if you happen to find an I.G. forum, then they'll most likely have posted their stuff on warseer. Mind you, there are plenty of 'one off' armies and neat things like that on I.G. specific forums, but personally I feel that warseer has 'enough'.
Anyways, it'd be good to see suggestions though...
