There are many "help" links on the web site, but most of them lead to "help not available" message.

I need to disable all the help links (in non-admin mode) that lead to "help not available" message.

I understand that checking the existance of the help files when rendering the page will cause some productivity losses. I suggest 2 solutions:
1. Load and cache (in a hashtable) the list of the help files on application start.
2. Make this check optional (add an option to Web.config).

It would be nice to populate the help system, but it's not the solution for this problem. When implementing site in a non-english locale it's needed to hide those links that do not have help in the needed locale.
