I have the defaults set to use the most advanced editor available. By editor, I mean where we type the messages.

You can switch between the most advanced and one with slightly fewer features if you like.

Simple click on the image in the upper right hand corner to switch back and forth. If you find one that you prefer over the other, you can set it in your User CP to always present you with the one that you prefer.

Let me know if you have any questions.
