What You See Is What (You Want) To See Now. Common pronunciation: "WizzyWatson" smile Unlike WYSIWYCA, WYSIWTSN is driven by user motivation. It's meant to allow for larger Tiki installations broken down into workspaces using Perspectives.
What You See is What You Can Access (do not show options that you are not supposed to see). In other words, list and menu items aren't displayed for pages or features, etc, that the visitor doesn't have permission to see.
What You See Is What You Get - it means while you edit the page you see it directly (as closely as possible) as it will appear after save (shows text layout and styling, etc. in the edit window). In latest Tiki versions we have integrated CKeditor to achieve that.
