The only issue I had was with the placement (Joomla 2.5 numbering) but I found out that, in my case, this was position 15. I asked the developers to update the instructions with a little more installation info. Think this would save them the hassle of helping people out with this little issue all the time as the rest is just plain simple.
Be advised that you can't make the box message longer then suggested. This will make it stop working. However, a longer message isn't needed, just refer people to your privacy disclaimer in the URL box if more space is needed.
