To be honest i haven't started using this, my first concern was that i wasn't able to upload large video files and i sent an email, i swear to god i got an answer in less than 3 minutes and i was satisfied with it, so i recommend this, really.
I am using this for a 4th year software engineering project, do i need say more? Well the support was custom made at no extra cost, greatest support team ever, they know their stuff and teach you. I personally would recommend this to US DOD if they use a form system for joomla. Bravo c'est Excellent.
