self certification - digital signature

[bryan]

I have some macros in Word 2000 form that have self certification. When I
open these forms in Word 2002 with Medium security, I can enable the macro. I
would like to check 'Always trust source', however this box is greyed out.
I can set security to Low, but that is not reccomeded.
Is there some other setting so that I can check this box and not have it pop
up every time?

Thanks,
Bryan
