Great job! This will be very useful for many users here.

I tried doing something like this list a while ago but stopped midway through due to plain laziness. I was also adding an away/inactive classification, as in 18+ days = "away" and 30+ = "potentially inactive" . The reason for such a high away day tolerance was to avoid classifying someone as away when they're busy due to work, I reckon that many situations can be solved before 18 days and thus chose that number. I did add that to avoid cluttering the list (I placed away and inac in their own mini list, or at least that was the idea).

So as I had some free time in my hand I decided to check all IDs and classify their status accordingly. Days since last login are in parenthesis.

Away: 0
Potentially inactive: somecoconuts (already in the list), masterwolf33 (100+), fakeyfakerson (62), Silvraph (42) and thewind32 (96)
