To set up an account, members just need their membership record number which can be obtained from the ward clerk, or which is also found on ordinance paperwork, and an email account. (A blessing when you've forgotten your username or password.)
(Not to confuse new.familysearch.org with www.familysearch.org.. The latter is a free database of genealogical records and pedigrees which can be accessed by anyone.)
