Although I have only been using this extension for a few days I am very happy with it. It is being used on a J 3.2 two language website and was easy to set-up. I would love to see a list module for event in the free version. The registration works flawlesly.
On the web I read a security alert about this product that was out-dated and was worried. I emailed the developer (Cyril) and he got back to me very fast with the truth and had other suggestions that most devs never mention.
Thanks for everything and supporting our community, great work!
