The Word documents can be read using MS Word 2007 or later. If you have a previous version then you should upgrade as previous versions are no longer supported by Microsoft. A compatability pack for earlier versions can be downloaded from http://www.microsoft.com/en-gb/download/details.aspx?id=3.
The PDF files can all be read using Adobe Reader available from http://www.adobe.com/uk/products/reader.html
Our preferred method of communication is for you to use the MS Word documents and to email them back to us. It's faster and more reliable than snail mail.
