Please note the #ifexist is considered an expensive parser function and each page has a limit to the number of expensive parser functions that can be used. Also, if the page you are checking for doesn't exist, it will be added to the list of wanted pages; even if it isn't supposed to exist. - Edit:

Fandyllic, the "or" is in the expression for #expr which does support it.
