Nothing like sending a doc to a client only to have them see a bunch of gobbledygook. I am using OpenOffice Writer, my client seems to be using some form of MS Word. In addition to .odt, Open Office will save in various flavours of Word: MS97/2000/XP (.doc) MS95 (.doc) Word 6.0 (.doc) (I have never had a clue which is the most modern/standard one.) He is sending me docs with a .docx extension, which I can open in OpenOffice, but will not allow me to resave as .docx. So we have no way of passing a compatible doc format back and forth. I could convert it to PDF, but that's inconvenent for him. In this, the 21st century, must I really find and install some other third party tool just to share documents with someone?
