From the developer: "EF Stands for EMail and Fax so EFGrabber is an EMail and Fax number parser for the web. This freeware version will allow you to surf the web using the software's built in browser but when you come to a page that has email addresses or fax numbers on them, it will store them for you and give you an option to export to text file when you are finished. This is a good way to build up leads and lists from sites that carry many faxs and emails such as your local chamber of commerce."
