New website...oops.

Posted December 14, 2017 @ 1:09pm

ADMIN ALERT: As mentioned in the recent newsletter, we're making progress on the new website. Part of that process included uploading a membership list for test purposes. Sadly, an unanticipated result is that the new website is sending its own renewal notices to people who's NAPARS membership expires this month, based on an outdated membership list. So, if you get an email that includes "NAOPARS" in the URL, it's not spam, but you can ignore it. Sorry about that - I have the IT people working on it now. Peace. -Wade

July/Aug ARJ mailing list to be built soon!

Posted July 7, 2017 @ 7:42am

Being an odd-numbered month, I'll be building the mailing list for the next ARJ on July 15. I've sent reminders to everyone whose membership expired lately, including a handful since the last issue. Anyone whose membership is active on the 15th will get on that mailing list, so now is a good time to encourage that friend to get on the NAPARS bandwagon! Peace. -Wade, admin
