Things have changed rather dramatically.  Just two years ago, it
seemed that the other planes would be used for rarely-used scripts,
most of them only interesting scholars (e.g. Linear B).  Now there are
several proposals which could become pretty relevant as soon as
Unicode is more widely used (if this really happens some day), for
example the alphanumeric math characters.

Hmm, I'll try to figure out the formal requirements for an ARG
submission.  Which is the correct address?

http://www.ada-auth.org/arm-html/RM-0-3.html mentions the address
ada-comment@ada-auth.org, but the ARG procedures
http://www.ada-auth.org/ai-files/minutes/arg-proc.txt request to use
ada-comment@sw-eng.falls-church.va.us.
