[Rack] Adding people to the secretary@ alias

[tdfischer at hackerbots.net]

Hi, rack!

I'd like to add a pair of people to the secretary at noisebridge.net alias
to help with philanthropist paperwork and RFID token stuff.

Henner: hzeller at acm.org
John Shutt: jds at riseup.net

I'm trying to distribute the load as much as possible and don't have
enough familiarity with the nb.net server to confidently not break
everything~
