Squarespace Websites Uploader

Squarespace has good forms builder, but unfortunately there is no upload field to store user files or docs. It may be useful for user images, screenshots, pdf-forms or so. Sure you may use some side services to organize file uploading: Wufoo, JotForm and many others. And while they have great builders and file uploads, sometimes you need more than 3-5 forms or 1000 form views per month with free account.  So we decided to make a small javascript plugin, which adds file upload fields to Squarespace forms and small service to handle these uploads.
