Thanks for the helpfile.
About the WikiIndexpage, I don't think it's ok to have only WikiIndix for languages like Japanese (with completely other symbols) or LTR-languages.
I don't understand the need for WikiIndex beïng verry static. Can't it be replaced by a string, wich is searched every time in the language pack (wiki.php) The file has to be called 'WikiIndex' , but on screen the user sees the translation.
(Since I'm not a programmer, some of my ideas might be extremely senseless. Don't mind telling me that. But sometimes a stupid idea can be the initial tought of a good one. Like the Earth having the shape of an egg, instead of a disk (but a little more modest))
