The dates are formated as YYYY/MM/DD and are based on when the Tracker learns of changes.
The SKILLS are recorded from the top 100.
The current IGN in use is displayed under Info/IGN.
The Tracker auto updates every 1-2 days depending on the cycle.
If a IGN isn't in the Tracker, it will automatically gather it.
If you keep getting this even though you know the ign exists, try waiting 5mins and trying again.
This can trigger automatically if the response is taking to long. Try refreshing the page and it should update properly.
