Administrators can protect pages and unprotect pages. The majority of pages on the wiki should remain publicly editable, and not protected. Pages may, however, be temporarily or permanently protected for legal reasons (for example, license texts should not be changed) or in cases of extreme vandalism or edit warring. There are two kinds of protection: * Full protection disables editing for everyone except other administrators. * Semi-protection disables editing from IP addresses and accounts less than four days old.
