Fetish Wealth's W-9

[Useless]

Has anyone been able to successfully submit Fetish Wealth's handy W-9 online form? I get this error:

Request-URI Too Large
The requested URL's length exceeds the capacity limit for this server.

I've emailed them twice about it, once being this morning, but I have no reason to believe that I'll get a reply to this morning's email any faster than the one I sent a few weeks back.

It seems like a nifty tool - much faster than mailing a printed version, but only if it works.
