The Big Black Bat
The extension loaded perfectly and kind of worked .... dropped an email to support and unbelievably they replied within 10/15 minutes and had my problem sorted within 30 mins!
All I can say is AMAZING! Plus, i'm probably going to need a few more extension for various things on this website i'm currently building ... so these guys will be the first port of call!
Seriously, if you need something like a Website disclaimer pop up then this is your answer, it's clean and simple and so far the support has been A1!
