2. As word processing software gets more sophisticated is becomes easier to submit your manuscript in a professional format. Please do not use these advanced features. The typesetting process works best with simple text from, for example Microsoft Word 97 or 2000. In the final stage of copy-editing we have to remove all of these advanced features and this sometimes changes the sense of what you are trying to say. This is time-consuming and may delay your article so that it has to be held back to a later issue of the journal. If you are submitting an article that you have formatted for internal use, please help us by removing any advanced features before you submit.
