Player On Line

[dopauls]

Is there a way to tell if a player is on-line at any particular moment?  If so, how is that done?

If they're in your Friend list you can tell when they were last online by looking at that. If they're in your Corp, the members list will tell you.

Otherwise, I think the only way you can tell is if you come across one of their ships in orbit, and the little green dot next to their name is lit.
