* Put a useful message for new admins on /about/more
I totally failed to realize this file was just defaults. I think
this message would be a good default for people like me.
* Revert default site description, expand comment
This will keep setup-related stuff from leaking into public views,
while still hopefully keeping over-eager admins from editing this
file unnecessarily before RTFMing. (e.g., me)
