The most important thing we liked about this software is its ability to organize all of our events in one place! We are able to pull information directly into each event page which makes everything so much easier for us as organizers/event managers!! I think there's nothing really i dislike or didn't understand well enough yet but if you're looking at doing an online ticketing system then definitely look no further than net site - they have great customer service who can help guide through any questions before purchasing (or even after!).
It has made managing my website very easy by allowing me to post updates straight onto pages rather than having them emailed out separately every week etc., saves time & money too because less emails go missing when sent via email vs being posted manually on individual webpages.
