User Session Synchronizer

a very clever solution that works flawlessly. great job

perfect work

This plugin works extremely well. 

I am seriously impressed that it does what it says it does. 

The only thing it needs is some better documentation for initial setup. Further, it needs documentation as to what the "User Verify" menu item is for, and the "Email Template".

I thought that was required for users to "verify" themselves to the secondary site.  I think it's just an extra utility to make sure users have valid emails. Seems unnecessary as part of this plugin.

Brilliant! Needs better documetnation
