As far as I can tell, Tuan never sleeps. Since purchasing Event Booking I have had two "supposed" issues but after checking the forums and submitting a service ticket I found the problem was only my ignorance. Both times Tuan quickly (and patiently) showed me that the feature I was looking for already existed. Then he showed me how to find and use it. I have been surprised by the speed of the help and the depth of the extension compared to other paid extensions I've since quit using. Event Booking is working just great for me. Go Tuan!
