    I think this is a great volunteer project for anyone 
who's interested in linux system administration. Let us 
know if you're interested in helping or learning. 
    We can meet up either at the next regular SF-LUG 
meeting (Sunday February 5 from 11 AM to 1 PM at the Cafe 
Enchante on Geary at 26th Ave) or at the Linux Discussion 
Group meeting at Noisebridge (every Wednesday evening 
from 6 to 8 PM) or both--don't worry about coordinating 
between multiple meetings, we'll take care of that. 
    Note that Michael is an expert Linux sys admin with 
a particularly good sense of best practices.
