@Phyllis You are right, the file size could be a problem. Putting the images on a web service (postimage; etc) and compressing the text odt file as an attachment to the post should keep the space taken up a lot. A generic contribution should only cover a section of a chapter in the manual, so there should be no size problem. But better to hear Sam's opinion as well. As for the danger of leaving a thread open without getting to Latex, it is true: it is a real danger. @Georgy I have never used Lyx but I see that it still relies on texlive. I was just thinking about the possibility that contributors don't want to have anything to do with Latex. LibreOffice is about not forcing users to install and learn other programs. Maybe txt would be better, but you can't keep track of the various contributors.
