404 Page for Typepad?

Looking for guidance in implementing a custom 404 page for a Tyeppad blog

[mevans05]

Does anyone have any information on how to implement a custom 404 page on a Typepad blog? I'm stumped.

i think they are stumped at typepad too!

this:
[typepad.com...]

will get you this:

Not Found

The requested URL /this_is_our_404_document was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

since typepad is a subscription service, perhaps you have access to support and/or a user's forum...
