I'm GMT -4:00 (Aka Eastern Standard Time) and weekends are probably the best for me (though with my schedule I'd probably have to drop out early).
Also, I'm currently reading through the rulebook and am finding the ranges for the weapons hilarious/stupid. A lasgun has a range of 100m, meaning that its maximum range is 400m which is only 40m further than an assault rifle autogun which has a max range of 360m. It gets even more silly when you compare the ranges to real life weapons. A Karabiner 98k (aka the rifle the Germans used in WWI/II) has an effective range of 500m. And if you stick a scope on it, the effective range doubles to 1000m! Now admittedly Dark Hersey range is not 1:1 with effect range, but the fact that a rifle from the turn of the twentieth century can have 2.5x times the maximum range of a lasgun should tell you how laughably short-ranged the weapons are in Dark Heresy.
Like I said before, I sort of planned on playing it fast and loose. I'm not going to hold the numbers in the book as Word of God so much as good suggestions. I'll try to make distance shooting realistic while still letting melee type characters be relevant. Shouldn't be too hard when the most common foe of an Inquisitor is cultists of the Ruinous Powers, who are not noted for being tactically sound.
Also, I've decided your Inquisitor is from the Ordo Obscura, which I definitely did not just make up on the spot. This way, you all can deal with a wide variety of foes, rather than getting pigeonholed into fighting ONLY Cultists or ONLY Demons or ONLY Aliens. On the flip side, this means I have a much greater variety of threats to present to you. I've decided the Ordo Obscura deals with unknown or previously unencountered threats, and they're also basically the Inquisitors that are on other, more important Inquisitor's shit lists, who are often dispatched to deal with what amounts to a fancy rebellion with a snazzy slogan or a cult to some unknown alien deity that doesn't actually exist. So when you actually DO find something that is a threat to the Imperium, you will have oh so much fun trying to convince people to deal with it.
