I've use Event List, GigCal and now this one and prefer JCal above the others. If you like to make quick event additions and still have the option for lots of configuration, this is the one!
Installs in a snap and the additional Spartan theme mixes with pretty much any professionally made Joomla theme around.
Thanks for the note. I just wanted to point out that for the vast majority of JCal Pro users, JCE, WYSIWYG Pro, TinyMCE and FCKEditor all work great.
I hope we also find a solution to your particular problem with editors and JCal on your site.
