802 MediaWiki can include a basic license notice, icon, and machine-readable
803 copyright metadata if your wiki's content is to be licensed under
804 the GNU FDL
or a Creative Commons license
. If you
're not sure, leave

816 <?php aField( $conf, "SysopPass2", "again:", "password" ) ?>
819 A sysop user account can lock or delete pages, block problematic IP
820 addresses from editing, and other maintenance tasks. If creating a new

850 Using a shared memory system such as Turck MMCache, eAccelerator, or Memcached will speed
851 up MediaWiki significantly. Memcached is the best solution but needs to be
852 installed. Specify the server addresses and ports in a comma-separted list. Only
853 use Turck shared memory if the wiki will be running on a single Apache server.

917 <p>E-mail address authentication uses a scheme to authenticate e-mail addresses of the users. The user who initially enters or changes his/her stored e-mail address
918 gets a link with a token mailed to that address. The stored e-mail address is authenticated at the moment the user comes back to the wiki via the link.</p>
920 <p>The e-mail address stays authenticated as long as the user does not change it; the time of authentication is indicated
