I have very little experience with svn. If i understand it correctly, it’s a server with the latest version of jME that you can connect to and automatically get updates. I wish to set up my jMonkeyPlatform to automatically get updated but I have no idea how to use svn. I’m running Ubuntu 10.10.
Uh, you dont have to do anything with svn to get the latest svn version 
Just enable the nightly update center and update jMP. The manual (F1) contains info on how to do that.
Found it, thanks
Edit: The update kinda broke my project, just as I expected. Hence the reason why I waited to upgrade until my project was finished I think I’ll disable automatic updates when i start my next project for that reason.
My finished project if anyone is interested: http://hub.jmonkeyengine.org/groups/free-announcements/forum/topic/my-first-jmonkeyengine-game-is-now-completed/
