No, it is an external program that doesn't actually relate to mule, it's a completely seperate application, there is no way to tell who is using it or not using it. I used to use it constantly, sometimes I still do, but it's rare these days. A lot of people used pencil and paper before these trackers came around, it's just a convenient way to do it without using paper.
Partially, this is exactly what the tracker is for, but instead of pencil and paper, you have it in a cleaner way using the Flash thing. Many users were already using paper and pencil notes for tracking it, so I thought it wouldn't be too different if I made that tracker. However, it went "evolving" and suffering too many changes, making it a more complex tool.
Is there a way to block players who use it? Sorry Im old school use your memory.
This is the reason what made me think if it would be wise to share the tracker with other users, as it might be considered "unfair" due to the colored plots help and events there. It's true that old school players are in misadventage versus the computerized player, but you should keep in mind that many players used the classic pencil-and-paper trackers even in those times. You have voluntarily chosen an different path, but you can't force others to choose that path too. I mean, if they used pencil-and-paper trackers already, they will use it yet and consider it the "normal" way to play.
It would be interesting to open a poll thread to know what kind of tracking they use.
