The ability to very easily synchronize user logins between different versions of the same site! This is immensely useful, and it means that people can, for instance use the same login to login on two different sites - logins,passwords etc are all synchronised automatically between the two sites. If an user is deleted or updated on one site, that information automatically updates on the other site. Very useful to do what a company like Amazon does ie use the same login across Amazon.com, Amazon.in, .co.uk. etc. Review collected by and hosted on G2.com.

Very little to dislike and I see only upsides to using this great little plugin! Review collected by and hosted on G2.com.
