FamilySearch Wiki:User IDEdit This Page
From FamilySearch Wiki
Your User ID will be visible to all users. Consider carefully what name you wish to be identified with. Using your own name is ok, but to maintain a level of privacy, it may be better to select a User ID that only describes you to those who know you well. It is best to choose a neutral, non-controversial name. No obscene or profane names are allowed.
Please visit the User ID Discussion page to add comments or suggestions for further development of the policy related to the User ID in the FamilySearch Research Wiki.
