I'm currently hosting a Minetest server with a couple random mods (because they were in the package repos). I plan on making some posts on Arisuchan/Lainchan and whatnot. Not sure how long I'll be hosting it, but when I'm done I'll make sure to put up the world file. The server's currently on resource gathering mode (non-creative), and the only "grief prevention" I've set up is a cronjob to take world backups, if that's a problem I guess I'll get some mod for that.

Enjoy the server (^U^)
