If there is no maintainer for sys-process/nmon, I would like to take that, since I'm using this regularly. Please just be patient with me, since it will be my first package. :) btw.: The email said "Due to bug #584246 the following packages have been dropped to maintainer-needed", but I cannot access this bug.
There no open bugs for nmon.
