[svlug] Hardware for a new server

Rick,
I have two (2) dangerous propositions.

1) Instead of new hardware, I suggest SVLUG go to a virtual hosting
2) If SVLUG insists on hardware, I suggest SVLUG setup a virtual host,
and host other Linux User Groups (as local as possible)

Dangers in both. Migrating to new hardware continues inherent dangers.
