[NSRCA-discussion] Article (series) suggestion for K-factor

Wed Jan 2 10:24:52 AKST 2013

If y'all ever have something to submit that you'd like published in the
Kfactor, I'd be glad to get it in the next edition.  Our monthly deadline
is the 1st of the month to have articles to me.  Please provide the article
in Microsoft Word (or Notepad or any text software as I can convert) and
any pictures supplied separately.  Make the pictures as high resolution and
bright as you can.  Where you want the pic inserted, simply put <<insert
pic1.jpg>> and we'll do the layout.  You can send it to my email address.
 Do not send via the list as attachments don't go through so well.  If you
have any questions, just let me know.

Regards,
Scott McHarg
NSRCA Secretary / Kfactor Editor (as of January's issue) / All around good
guy
