I have never found that Word software needed any support. It has its own Help glossary. "Support" usually means protection from internet viruses. I was told that files for uploading to Lulu needed to be in MS Word 2007 or later, and the explanation given was that the later versions enabled us to format headings and sub-headings to create an index, also the option to "embed your fonts".However, the earlier versions also can set headings and sub-headings and make them distinct.I never did understand what embedding fonts meant though I did it for the purpose of a print book. The book came out very small.Next Ebook I will just try to make a PDF file, There has to be some way of doing it.It would be helpful to know whether Lulu can upload or process an Open Office file. I have used Open Office and found it pretty much the same as MS Word.
