We balance a lot of time between all servers and forums. Just the other day I was on Teva for about 2 hours banning bots and talking to players. Most of the time I deal solely with Apoline. As I also do a lot of forum management with Cretz. It's a big job involving a lot more than just being in game and running events. I have forums, bot investigations, bugged players to fix, fansites to monitor, events to run, harassment issues to deal with, player disputes, etc et infinitum.
I tend to be the most active because I sleep the least. 3 to 4 hours a night.
