Editing Beginner's Guide to Mediawiki for the Test SB Wiki Page (section)

== Protected pages ==
Pages that are protected cannot be edited by anyone except users of a specific group. Protected pages will instead display "View source" instead of edit. In that case, to edit a protected page, contact a user who has permission to edit the page. The default protection levels are as follows:

None (allow all users)
Autoconfirmed (prevent edits by new and unregistered users)
Sysop (prevent edits by all users except administrators)
Other types of editing
With wiki edits you can start a new page, move (or rename) a page, or even delete a page:

Help:Starting a new page
Help:Moving a page
Help:Deletion and undeletion
Remember you should always aim to improve the overall contents of the wiki with your edits.
