had this problem...
I wanted to use a module with Accordion effect to make a bunch of categories...and then link to an articles who had another extension (3-d slideshow) to show the actual slideshow.
it didn't work, because the articles was "hidden", could get it to work with menu-linked items (visible) - but couldnt find any nice HTML module...
This did the job !!!
easy to use, and my module popped up exactly where I wanted it, gratz to the developers - I am going to contribute !
I read through many posts to see that I actually had to have my article being a jevent article for the big calender to show up in my Calender item... after that - was a blast !
Enjoy - keep up the good professional work - I might soon upgrade to a gold membership !
