Adobe provides a version of their Acrobat PDF reader that allows you to easily
fill out forms that come in PDF format, and it's FREE.

You'll find it here:
https://acrobat.adobe.com/us/en/acrobat/pdf-reader.html

Just download Acrobat Reader DC, not the Acrobat Pro DC. You can easily see from
this Adobe web page which version you need, and if you just want to fill out and
sign PDF documents, you only need Acrobat Reader DC.

If you are filling out our waivers for our competitions, you can easily create
semi-filled-out versions of the waivers with your personal information and save
them. Then just edit them and save them under a new name for each specific
competition without having to fill out every field every time. See instructions
above.
