Welcome, Eileen. Glad to have you with us.
Be sure to use the help pages... https://www.wikitree.com/wiki/Help:Help_Index
and post your questions here on G2G, whether for genealogical assistance or the how to’s of using WikiTree. There are no dumb questions. You find lots of capable people to help you out in both cases.
I hope you find being a member of this community as profitable as I have.
