I've definitely staled at least twice because the internet company have messed up installing my home line THREE(!) times, so I'm having trouble at the weekends as I can't get net access. I expect it should be sorted for next weekend.
Is it absolutely necessary? There are many players that want to play as many turns as possible. I'm afraid I can't make this decision myself; everyone with an opinion in this matter should state it and Niarg, can you specify how important it would be to extend the turn time?
I'm not too fussed either way, although I'd like to request that after the ~10 am Saturday turn generation the next hosting be delayed until Monday am (a one-off 48 hour turn would do it), as I'm going to be away from home for a couple of days and don't think I'll have Internet access.
It wouldn't be necessary, just convenient and I am happy to wait until there are a couple more requests. Consider this an invitation to comment on the turn time rather than just wait until everyone is rushing their turns.
