This application add-on to Joomla is absolutely one of the best I've ever used.
We have gone from offering a straight table-style list of our sermon history that was a bit of a pain to update - especially at series end, TO having sortable, well-presented, easy to use and update, beautiful method of delivering content to our site members and visitors.
And the support? Unparalleled in the open source community. Just the best, most responsive group of folks I have come across!
Can't say enough good about this application.
