who rank explorer/elder/whatever

You got the idea.

++C

grep 'Explorer' who (and if there's too many lines in the 'who' to use grep,
use grep 'Explorer' who max 50 and then min 50 for example)

I don't know if that was the point of your idea or was the idea to list all
the people who have even access to some special rank and isn't using the rank,
but the grep should handle most of the cases i think.
