The ability to allow visitors to upload their files to forms is very important indeed. We will keep you informed of this feature progress.larry commented
It would be great to have a form that includes an upload button. That way customers can send us there artwork as pdf., jpeg, ai files or anything directly from our site. A form attached to the upload button would be nice so that they are required to put there information and details of size etc in a message. Lets make it happen guys!
We are happy to announce that we started planning a Mailchimp integration.
Thank you for all the votes.
