underline text in a form
I am an adult literacy teacher and I want to create a word search on the bottom of an existing vocabulary/spelling PDF form which already has text boxes for students to type their answers to questions. This will be posted to an educational website for my students which is similar to Facebook, but restricted access only to the members of my class. This is their homework, but they see it and do it online. Many of my students don't have printers, they will do it online and resubmit the finished homework to me on the site. I am looking for a way for them to underline the finished words in a word search. Here is a sample:
N C L A S S R O O M R A I N C O A T B E L O N G
O A N Y O N E S E A A N T C E N E W S P A P E R
T B D R I V E W A Y I P L A Y G R O U N D M C A
Any ideas, please?
