Hi, again, jodahministries! 🙂 Thanks for all your questions and putting them in separate threads. That’s really helpful for us!
The default visual editor for WP uses TinyMCE, and our plugin is fully compatible with the built-in visual editing functionality. Is there any particular issue you’re having?
Also, I’m a little worried when you say that “the built-in editor does not allow for WYSIWYG editing”. Would it be possible for you to post your System Info, found in the black box at the bottom of the Help Tab of the Events Calendar Settings page, so I could get a better idea of what’s going on with your installation?
Thanks!
