I usually try to figure a schedule for my games by PLAYER availability. That said, I do have a couple of caveats to that. Fridays are out due to prior game commitments. Additionally, I am a contractor that works with the military and National Guard regularly, so every now and then I may be unavailable for anywhere from a weekend to a few weeks at a time. However, I usually (almost always) have plenty of warning as to when I would be away/out of 'comms'. The simple answer would be 'I am available for most evenings (US Mountain Time) between Sunday through Wednesday' (Thursday and Friday are the normal hectic days at the shop).
