Custom Mailing List error page

[Fenice]

When a user don't fill the field to subscribe to my mailing list I receive an error page.
How can I use a custom page? (i'm using futurequest mailing list program). Thanks!

What do you want in a custom page?

It should be possible to make any form that would get the subscriber's e-mail address and send the correct subscribe message to the subscribe e-mail address.

I guess I don't understand how you would like this subscribe page to behave. Under what circumstances should it issue an error? What should the error look like? I have a script I've recently written (referenced here: http://www.aota.net/ubb/Forum3/HTML/001664-1.html ) and it could possibly fit the bill. I'm just not sure what you want.
