I've still not yet heard a consensus or approximation thereof ... yet,
that [www.]sflug.org should be the canonical (or not ... or when).
In any case, now with some config changes in place on
web server, and awaiting delegation of DNS ... once delegated,
http[s]://[www.]sflug.org/
will at least have somewhere to go:

$ curl -s -I --resolve sflug.org:80:198.144.194.238 http://sflug.org/  
| egrep -i '^(HTTP/|Location: )'
HTTP/1.1 301 Moved Permanently

There are also some other domains in DNS, e.g.:
[www.][ipv[46].]sflug.org
AXFR is open to all for sflug.org. from ns1.sf-lug.org.

Still don't have proper certs there ... that would be after someone
provides key(s) (securely) and cert(s), etc. ... or after DNS is delegated.
