That raises another point. Tuesday and Sunday seem to be largely ok - what time?
Evenings are more or less my only fixed time as have two young children climbing over me otherwise, or am at work! How about from 19:30 onwards, gives us about 3-4 hours max which is probably all anyone really wants to raid for. If we're all on by say 19:00 then we can always start a bit earlier.
Timings given are London time, adjust for zone accordingly
