Testing your documents should be an integral part of your plain language writing process. It should not just be something you do after the final version to see if it worked. This is especially important if you’re writing to hundreds, thousands or even millions of people and work in many different formats such as pdf, which is one of the mos popular, and that’s why is important to have a program from https://www.sodapdf.com/pdf-editor/ to also help with this. The information gained in testing can save time in answering questions about your document later.
