Please check in the PR#173730: [PATCH] Added rc.d script for net/vnstat port

[Yuri]

http://www.freebsd.org/cgi/query-pr.cgi?pr=173730
I contacted the maintainer Dennis Herrmann <dhn@> on Nov 09, 2012 and 
got no response in 2+ months. This PR is also assigned to dhn@ with no 
response.

What is the policy of detecting unresponsive maintainers? There are 
quite a few ports owned by dhn @. Should all of them be reassigned to 
ports @ ?
