The KB is currently in the process of moving to a new WYSIWYG editor. As we transition, there are currently three editors to choose from within the KB.
For your own group space, you may prefer to use only the newest editor (TinyMCE), or to allow authors to switch between multiple editors. The option to set which editor(s) are enabled for your group space is described below.
Note: Of the editors enabled for your group space, an individual author can choose which is their default by updating their user profile. Please see KB User's Guide - Home Tab - My Profile for more information.
