Short Answer: You have taken the FIRST step ...
As, you are asking THIS 'Question' in this "Community.FamilySearch' Forum ...
It is evident that ...
You are (ie. have become) a "Registered" User/Patron of "FamilySearch" ...
That IS all that is needed/required.
EVERYONE can view and access 'FamilySearch'.
One DOES NOT have to be a Member of the Church to view and access 'FamilySearch'.
'FamilySearch', is FREE, to ALL, to view and access.
Question: WHY do you ask such, a question?
the exact same way anyone does. Family Search is open to the world - and has been for many years now.
"Question: WHY do you ask such, a question?"
Jeff might not realize that community.familysearch.org is just a subdomain of familysearch.org. He may be coming into the FS Community directly via a bookmark or some such (after all it IS externally searchable from the Internet).
He just needs to try going directly to the familysearch.org website and use the same ID password he does to get in here. From that point it should be fairly obvious.
Just to add to the replies already given, members of the LDS Church can use a public account, but more likely work within one designed specifically for them. This enables them to view temple / ordinance work that has been carried out on their relatives / ancestors.
For those who are not LDS Church members (like me), there is a great deal of benefit in using the "public account" version of Family Tree. I have found many of my relatives already entered in the database, saving me much time in my research. In return, I have added thousands of names that were not already there and found it very satisfying to work on this collaborative project.
