After some experimentation and failure on my part, we have found that our group needs to find an external GM rather than rely on ourselves to do so. We are currently 5 players strong, varying from relatively knowledgeable to extremely learned in 40k Lore. Two of the players do not wish to speak and as such a Text-Based communication system would be preferable. While free at certain points during the week it appears to be a group consensus of a weekend game being the most adequate time. As a forewarning, most of us are fully aware of how the characters may be effected by the setting and (unless upon request, none of us mind) will likely act in a manner that fits the Lore, including the more mature themes of Chaos.
