Appearance
The VisualEditor option is intended as a user-friendly, "What You See Is What You Get" (WYSIWYG) editing aid allowing one to edit pages without the need to learn wikitext markup. It is only available to registered logged-in users through an opt-in choice available through the "Visual editing" option at personal preferences.
