Do NOT ask a volunteer to do anything outside of his/her area or to do anything for which he has not volunteered.
Do NOT request the same information from every volunteer listed in the area of your research.
Leave a Thankyou or comment in the Comment section of the Volunteer listing page.
I'll do look-ups at the Pikes Peak Library and do photos/research at the Air Force Academy. I'll also do tombstone photos in the county. If you need something farther afield it may take a while but message me and we can work something out. All travel is weather dependent.
