What does a tracker have to do with Permissions?

posts: 26

Early in the page on Group permissions is information about setting up a tracker.

I understand a "tracker" can be used for arbitrary database items, but it is not apparent in that section why a tracker should be assigned to a group or what is often in the tracker. Its location near the top of the Group permissions instructions implies that it might be desirable or mandatory, yet it is not apparent how a suitable tracker should be created.

The present phrasing makes the tracker section at least a speed bump; if a tracker is mandatory (or the reader trying to set up Group permissions thinks it is mandatory) then it's a roadblock.
