This is fabulous! I was using Nuance PDF Converter, which has worked fine for many years, but it couldn't handle a couple of the 2013 IRS forms...So I did them here. And it worked!

Easy Forms It has been good, but the saving of the files is not that easy, have to upload document every time you want a new copy. The easiness to write pdf's and print them out. The documents are not categorized and it would make it easier to find.

What is PDF file security? While PDF encryption is used to secure PDF documents, so they can be securely sent to others, you may need to enforce other controls over the use of your documents to prevent authorized users using documents inappropriately.
It means the file is protected in some way, there are restrictions on what you can do with it. “If you receive a PDF that is protected by security features, you may need a password to open the document. If a document has restricted features, any tools and menu items related to those features are dimmed.”
