I've been following FlightGear for many years. Sometimes I just limited myself to "using" FG instead of actively being involved on it, so the newsletter was a good place to keep in touch with the latest stuff. However in the last few years/months the newsletter has seen less and less contributions. Maybe it's a general lack of interest on it, lack of developers who post their latest progress on it or maybe just a general lack of writers. I'm not here to discuss the reasons, but to propose a solution. Instead of a monthly newsletter, maybe a quarterly or even a biannual edition would be more benefitial. Just have a look at the latest issues of the newsletter - they are just a paragraph or two long. With a bigger gap between editions the newsletter might get more protagonism, "transforming" into something like a magazine.
I haven't contributed enough (or long enough) to this project to have any relevance deciding this, but maybe some people more involved with the project or the wiki specially find it interesting.
