Making forms which Adobe can convert into an online form

Adobe's Form Wizard tool can turn your word-processor-generated PDF into  a form.  Note that this tool is only in the full version of Adobe Acrobat (not the free Reader  version). 

The exact process for running the Form Wizard depends on what version of Acrobat you're using, but some tips on how to ensure that the wizard's conversion will be successful, are below and at (starting on p.3).

Checkboxes can be made using one of these:    (Unicode Character 'WHITE SQUARE').  These will let the user check as many as they want. 

Radio buttons can be made from one of these: (Unicode character 'WHITE CIRCLE').   If you want a form on which you can select only one option, put a group label above them, like this:

Hair color



Fill-in-the-blank fields must have labels to the left of, or under the underscores.  So the following won't work:  

Name                                    Date of Birth
