Manual Delete

For Admins, "annoying" pages such as those started with "www."s or "http:"s cannot be deleted properly by clicking the delete tab. You have to put this address on the address bar:

http://www.aboutus.org/Special/wiki/delete?title=

and enter the page name (like www.exammple.com) after the equal mark, i.e.

http://www.aboutus.org/Special/wiki/delete?title=www.exammple.com

To see the content, change the "delete" with "edit", i.e.

http://www.aboutus.org/Special/wiki/edit?title=www.exammple.com

To see the history, change the "delete with "history", i.e.

http://www.aboutus.org/Special/wiki/history?title=www.exammple.com
