I have worked worked with Unclaimed persons, Random Acts of Genealogical Kindness and Record A Grave organized by Jon Anderson. John posts cemetery transcriptions that we volunteers transcribe to ancestry.com, findagrave.com, and interment.net. I really enjoy working with him.
I have volunteered for RAOGK, however I have a sour taste in my mouth from one requester. I searched the major newspapers and historical society for a obit for a lady. I emailed her back to tell her I am still looking and to advise her that so far I had not located anything. She wrote back and accused me wanting money to release the orbit. I have not responded to her email, obviously she is not quite right in the head. Other than that incident I have enjoyed "spreading the genealogy love". Just think of all the records we could make available by each of us volunteering a few hours a week!
