Summaries for SIGNUM Newsletter?

[David G. Hough on validgh]

Once again I've been requested to provide summaries of numeric-interest
discussions for the ACM SIGNUM Newsletter.  Once again I can see that
I am unlikely to get around to doing so.  However, I would be glad to
send the accumulated numeric-interest archive (1.3 MB) to anybody who would like
to distill one or more subjects into written form for SIGNUM.  My contributions
to numeric-interest are in the public domain unless I indicate otherwise,
and I presume the same applies to other contributors.

By the way, anybody who is tired of receiving numeric-interest messages can
send a request to be removed to numeric-interest-requestavalidgh.com

NCEG has its own electronic and postal mailing list; these are separate from
numeric-interest although there's some overlap in subject matter.
Tom MacDonald maintains both of those (tamacray.com).
