Announcing: valhalla-spec-experts group

Several people tried to subscribe to valhalla-spec-experts, and were 
surprised to get rejected.  So let me clarify what's going on.

The valhalla-spec-experts list is publicly READABLE, but not publicly 
SUBSCRIBABLE -- the membership is limited.  Now, lots of folks are 
interested in subscribing not as members of the EG, but to get updates 
on a timely basis without polling the archives, which is totally 
reasonable.  For lambda, we had a lambda-spec-observers list which 
received copies of the traffic to lambda-spec-experts.  We plan to do 
the same for valhalla, we just haven't yet gone through the 
administrative work to do so (and I'd rather make some technical 
progress this week than futz with mailing list provisioning.)  So it 
will take some time to get the -observers and -comments lists up and 
running.  So please be patient!
