00905: $AuthorPage does not fit PageExists() format
I noticed this first in the Author Contributions cookbook but PageExists(
$pagename) does not attempt to wiki-ize the pagename before using it.
$AuthorPage is stored in "Group/Full Name Of Author" syntax.
using PageExists($AuthorPage) will fail because of this.
Propse that PageExists be changed to parse
$pagename to proper wiki standards, "Group.Page", no special characters (except hyphens), no spaces, etc.
