TinyMCE adds what-you-see-is-what-you-get (WYSIWYG) html editing to textareas. This editor can be enabled/disabled without reloading the page by clicking a link below each textarea.

Profiles can be defined based on user roles. A TinyMCE profile can define which pages receive this TinyMCE capability, what buttons or themes are enabled for the editor, how the editor is displayed, and a few other editor functions.

Lastly, only users with the access tinymce permission will be able to use TinyMCE.
