Subject: [xwiki-users] mail plugin

I saw the default installation refers to some MailPlugin.....

com.xpn.xwiki.plugin.mail.MailPlugin

A google on this only revealed a bunch of checkins.  How do I use this Mail Plugin?  I am assuming it is to register for notifications on pages?  I saw another plugin that I would have to install(and frankly, I tried but the instructions refer to stuff that isn't there or I can't find in xwiki like Xwiki.Toolbar page).  Any info on mail plugins would be appreciated.

thanks,
dean
