WikiGnome

TIL about WikiGnomes:

A WikiGnome is a wiki user who makes useful incremental edits without clamoring for attention. WikiGnomes work behind the scenes of a wiki, tying up little loose ends and making things run more smoothly.

Some of the most valuable work can be the tiny changes that leave things in a better place than they were found.

Also, sounds a little like prutsen.
