If you are referring to my earlier words, I should say my suggestion has been misunderstood.
The question about tools used was to get a clue for opening the PDF to read on GNU/Linux. The PDF won't be of much use if it doesn't open for many. I'm sure there are plenty of GNU/Linux users in this community.

The other suggestion I made was about putting up the drafts of newsletter available to all volunteers so that others can contribute not only with respect to the text content, but also through design, media and most importantly the structure of newsletter. This helps in easily inviting other contributors to contribute in whatever ways they can. It also helps in inviting ideas and participation that would continue on to the next one. The great thing about Wiki model is community and collaboration. There's much fun in collaborating on a newsletter which in turn is also about collaborative projects.
