CGIemail error pages...

Hello.

I'm working with cgiemail, and I have a relatively simple question that I'm hoping someone out there might be able to answer.

In the documentation (which can be found here), it explains how to set up an alternate 'success' page. But I'd really like to set up an alternate 'error' page, especially for the 'required field left blank' errors. (Other errors aren't going to be all that common for regular users of a mail form, so I don't care quite so much about those.)

So, does anyone know if it's possible? And, if so, how? Or do I just have to put up with the ugly, text-only, error pages that don't match the rest of my website at all?

Thanks in advance!
