One of the main advantages of using PDF forms, as against, web-based forms is that the PDF will always look the same regardless of which operating system or web browser is being used.

When it comes to delivering PDF forms, there are more options than with a web-based form. You can email the form to your audience or perhaps include it on a CD or DVD.

Forms have been a feature of Acrobat since version 3. However, the forms features available in Acrobat 8 are a significant improvement on anything available in previous versions.

Acrobat has traditionally been a "magpie" application, relying on other applications to create all of its content. Now, however, forms can be created in Acrobat based on a wide variety of pre-created templates: invoices, timesheet, expenses etc.

When using forms created in other applications as the basis of an Acrobat form, you can now choose "Run Form Field Recognition" form the "Forms" menu and Acrobat will examine the layout of the form and create interactive form fields automatically.

Adobe Acrobat 8 Professional's Scan From Paper feature also allows you to create an interactive PDF form that is based on a printed document.

After you have created the basic form and perhaps had Acrobat automatically generate your text fields, you can add all the usual form controls, such as check-boxes, radio buttons and combo boxes. Then, to complete the form, you can add a submit button.

The advanced menu in Acrobat 8 Professional contains a new feature ("Enable Usage Rights in Acrobat Reader") which allows Acrobat Reader users to fill out your form and then save the form data. Normally, this can only be done with a full version of Acrobat Professional.

To send the form to group of recipients via email, just choose "Distribute Form" from the "Form" menu. A Microsoft Outlook address book can be used to generate a mailing list or you can just type or paste in a list of recipients.

Acrobat 8 Professional now contains a facility for storing each of the returned form in one place, called a dataset. As you open each returned form, a dialogue box appears prompting you to add the form data to the dataset.

When you have got back all of the completed forms, you can simply open the dataset where they have all been stored and then export the data in a neutral format. Just click on the Export button and choose whether you want to export as a .csv or .xml file both of which can be imported into a variety of programs for analysis or storage.
