The best I can think of is:
http://libregraphicsworld.org/Which is not the successor of the magazine, but somehow the original implementation of the magazine idea...
It's maintained by Alexandre Prokoudine and I wonder if he would like to have people contributing to his efforts...
(During the last few years he has been focusing more on pushing the news from the projects themselves and produced fewer articles on this platform).
Personally, I would be interested in contributing to a magazine that is more geared towards the life of the projects in the libre graphics world rather than creating an artsy/research magazine on libre graphics practices.
But I'm not a good contributor... and, most of all, I don't want to do it alone.
