You forgot "pipe open".

I've been wondering that too.

But that one did not offer to summarize back to the group, so
it was "worse" than this one.
But the "if interest warrants" part still leaves me wondering
if emailed answers will make it back here or not...

Or with a _promise_ to summarize back to the group.
(without qualifications that will leave prospective answerers wondering)

Have you (the OP) seen the Posting Guidelines that are posted
here weekly?
The guidelines are meant to help you avoid being ignored:
Asking for emailed answers
Emailed answers benefit one person. Posted answers benefit the
entire community. If folks can take the time to answer your
question, then you can take the time to go get the answer in the
same place where you asked the question.
It is OK to ask for a *copy* of the answer to be emailed, but many
will ignore such requests anyway. If you munge your address, you
should never expect (or ask) to get email in response to a Usenet
post.
Ask the question here, get the answer here (maybe).
