As genealogists we often question the source of information about a particular ancestor, the reliability of the information, and whether the submitter is a distant relative-questions that can be resolved by communicating directly with the submitter.
OneGreatFamily has designed a feature so you can contact other OneGreatFamily members and communicate with them about records and other genealogical related information.
As you bring up the edit box for a particular ancestor you will see an icon in the bottom left hand corner of the edit box that says "collaborate," click on this:
You will then see a list of the groups that have this record on their tree. Click on one of the groups listed and then the username listed below the group. You will see the group owners name and email address listed in the space provided.
