Thank you for that last input. Unfortunately the said files are designed to be opened on anonymous computers, so that method is not an option. Thanks anyway though.

OK, it's certainly more convenient to distribute the document as a PDF.

However, if (at some point) you want to distribute a Word document, you can turn off spellchecking for the entire document by selecting the content (Ctrl+A) and then choosing "Do not check spelling or grammar" in the Review tab | Set Language dialog box. (It's even more practical to set this option for the styles you are using.)
