here is the simple way that i have always done this. i fill out the form and then click file then print then on the name of the printer, i select adobe pdf and then it will "print" it and allow you to save the new pdf into whatever folder that you want. you wont be able to edit afterwards but the info is saved and you didnt have to do anything extreme. i dont know if it is a certain adobe that allows me to do this but it is what i do for a lot of docs.
Found this on another site and it helped me. I have Adobe Acrobat X and others in the office have regular Adobe Reader. They can now edit the forms I create and save them.
"If you are using Adobe Acrobat X to make the form, set all the fields as you want them, then click File, Save As, Reader Extended PDF, Enable Additional Features. The resulting PDF form can be saved when filled in, if opened in versions of Adobe Reader before XI."
