I manage several high profile Joomla based websites that demand a high quality event management system. One of these sites was recently featured by Groupon.
Is there a lot to configure before using RedEvent? Yes. Probably more than most components. BUT, you don't get to have all these features AND complain that you have to do a little work to get things looking the way you like.
I suspect that those that have complained about the "bugs" don't really know what they are talking about. Just because something doesn't work exactly as you would like it to, doesn't mean there is a bug!
I have had to interact with the developers on several occasions. I have found them to be professional, competent and responsive.
Thank you RedComponent.com team for creating such a great Event Management System - Bravo!!!
