Rename a wiki page
You can rename wiki pages. Browse to the drop-down menu More functions and select Rename. You can now adjust the page name in the editor window. Clicking on Rename will save your changes.
Note: When renaming, you can re-link the URL of the old wiki page (defined by the title) to the new title (Redirect existing links). In case you have already communicated the page URL to someone, this saves you the effort of sending a new link to this page.
