FillAnyPDF allows you to upload any PDF and turn it into a fully editable form.  This has tons of applications for your church – youth trip permission forms, children's ministry volunteer applications, small group covenants, etc.

The service is free but is noted as being in beta.  I applied it during the recent Radicalis conference that was largely hosted online via streaming video.  Rick Warren's notes were in PDF format, which I promptly uploaded to FillAnyPDF which made them fillable online.  A great way to save paper and archive conference thoughts! See my usage example here.

The website lists the following feature sets:

• No software is needed to fill out forms. Everything is done online.
• Fill out PDF Forms online with variable font sizes and colors.
• Sign forms just by typing your name. FillAnyPdf provides the traceability necessary for the "digital signature" to be valid.
• Share blank and filled forms with coworkers or anyone you want.
• Invite people to fill out forms. You can customize your message to each person or send a group invitation.
• See exactly who filled out which form and when. If you invite people to fill out a form, you can see exactly which form they filled out.
• Any PDF may be used regardless of the software used to make the PDF. The PDF does not need "fields" to be added to the form. The entire form becomes fillable when it is imported.
• Paper does not need to be printed, saving you time, money, and frustration. It saves a few trees and reduces your carbon footprint as well.
• White-out and Redaction tools let you modify old forms to get just the form you need so you don't have to find the original or create the form again.
• No Scanning or Faxing
