I've been noticing that some writers recently have been uploading thier work in docx and odt forms. The site marks the file type as unknown however if you have the right software you can download and read it. To download a docx you would need Microsolf Word 2007 and up, to read odt you would need Open Office. Its like they were using an older version of Microsolf, then upgraded forgeting that by default it won't save a file as a doc instead it saves it as docx. There need to be a tutorial on the upload page for written work that show them how to convert these files into txt, doc, rtf, or pdf. Because while I can download format like docx and odt I know that others can't, and they shouldn't have to download or buy a new program just so they can.
