Giant gravedig, I'm aware of it, but I'm just letting everyone know there are still working links to the server and client.
http://stuff.fragmentedforce.com/jduno/ - the server and client are stored there, there are some improvements over the last update I mentioned here, as well as a management console that runs as a service, autostarts the server on boot, and lets you start and stop the server at will as well as restarting it if it crashes.
I haven't worked on JdUno in a long time, but to this day there is no permanent host for it and while I host it temporarily when people want to play, there hasn't really been as much interest in it as I'd like, so that's why I'm bumping this now.
If there's enough interest I can host a semi-permanent server at home, however it can go offline for a couple minutes every few days when I reboot the PC. I see no point in doing that however, if there's not a lot of interest.
Edit: Also, it's fully skinnable now, with an easy-to-use skin editor loosely based on Game Maker's UI.
Also, a slightly outdated version of the GM7 editable can be found here:
http://stuff.fragmentedforce.com/GMEDITABLES/GM7%20-%20JdUno%20Online.rar - it includes some other things like an autoupdater, which are no longer included in the main rars since I'm no longer working on it, however if someone else wants to develop it further, I'd be happy to provide the newest editables.
