User Sync plugin

Hi

I’m running a website for golfers that currently has two functions that require user sign ups.

One is for golf lessons and the other is for affiliates. I need to also add a membership but I’m concerned about too many plugins / registration combinations on one site.

Would the user syncronization plugin allow me to build a separate membership wp site and link the users from the golf site?

Does the plugin actually copy the user info across to the new site and if so does it copy complete user profile info or just user names and passwords?

Cheers

Darron
