It's a good plugin if you want to do the basics, but anything advanced or complex you will need to know code or pay 120 euros to have the code made for you.
Shame really as I thought it would have done what I needed it to from reading the documentation etc, but too many restrictions.
I have to disable a Role Management plugin to make this one work, but support has been ok to get it actually working on the site, just a shame we can't get it to how we need it without paying a big bill.
Alas, we've had to bin the plugin and use a different service. So wasted our money really.
