What do you need? You can add/change fields using the manage forms to customize. It does not currently have some of the field options, but we do hope they will come. They have been requested of the development staff.
Since custom forms does not have all the necessary elements as yet, is there a way to use HTML snippet as a workaround? I need a form that will submit the content to an email address. Is there a way to customize my HTML form so that it works?
