Don't use the page name edit or files or print or msword. These are pre-taken and won't work when linked to. Instead, prefix these with something appropriate – such as AIFiles, not Files. You can still edit/delete anything put onto these pages, however.
Referring pages, the code {{Backlinks}} shouldn't be used if a page is linked to too often as it is got when the page is loaded. If there are over, say, 10 entries, put extra links under a Links heading (as noted in the Default Page layout), instead. this helps speed greatly, and usability too.
