Last year I signed up to SS forums and the STPRAdmin mentioned a need for volunteering. I am interested in helping and have an ARA license now, but the STPRAdmin has not replied to their PMs. The STPR signup link at this page:
Facebook is probably the best spot(along with their website) for information. I don't think Volunteer registration is open yet. According to their last Facebook post- "It's time to start planning what you are going to do June 1st and 2nd. Although we aren't quite ready to pre-register you, the jobs have not changed. To refresh your memory, you can go to stpr.org and click on the volunteer tab. And the job descriptions will appear. Tell your friends and watch this page for when we are able to open registration." Thanks for Volunteering.
