well one way is to have a checkbox under a different name,
and have a hidden text field with the original name
and prior to submitting the form, check if the checkbox
has been checked, and set hidden value to YES,
if not set to NO, then reset the checkbox to false,
so it doesn't get returned,
Ex. If checkbox name is "WANTSPAM" make it say
and have a HIDDEN TEXT field NAME="WANTSPAM"
Have an OnSubmit="" event in the form, which
will check WANTSPAM-CK.checked for true and
assign "YES" to WANTSPAM, otherwise assign "NO"
to WANTSPAM, then set WANTSPAM-CK.checked to
