Another quick matrix-question...

[Trojan]

What is the 'etiquette' regarding this? I only have to save during a turn if somebody else in the household wants to use the PC and that's not often. Why would somebody need to be saving repeatedly during a turn in a small scenario? Presumably there is a reason this is registered and reported at the start of the subsequent turn.
Does this also register if someone 'exits' without saving, which I assume is considered 'bad form' as one could re-play a poor move?(Although I did this once accidentally when I was being hassled to get off the computer!)
