Also, without considering a possible chat ability, do you think 15 seconds is reasonable for a turn? I guess something like 30 seconds isn't bad. Just didn't want one user waiting forever for the other.

I apologize for the missing explanation, the last known activity time is the time since the scenario you are running recognized a change saved to a user's UserInfo. N/A means it has not noticed a change since you loaded the scenario. How it works, a thread updates a value every 5 seconds or so (just to create activity/changes to be noticed, indicating you are online). It should be noted that pausing the scenario will pause the thread as well. And resuming the scenario may reset some last known activity times to 0 when in fact they may be older than that.

Well I been on this first hour and played with a few of you. But I really must force myself to study for finals... Maybe in the future there can be times set when a group of users can get on to play

@Entity1037 Did you have trouble with one of my other scenarios with it telling you that? Do you have trouble with other peoples' scenarios with highscores or anything?
