After finally getting guest rank auto-rankup to work, the survival port is ready for public testing. Connect to smp.ngminecraft.com:25555 and read /rules. Instructions for ranking up will be displayed after reading the rules.
The survival port sports a customized version of mcMMO with many other features to come. There is a no-build zone that extends about 250 blocks from spawn, and you will be notified once you get past this border.
The rules right now are pretty much the same as the main port, but these rules will be refined in the near future.
Also, I’ve removed the super-high-resolution Dynmap and put back in the standard high-resolution setting. The super-high-res mode was found to severely kill server performance, managing to exhaust all of the server’s RAM in less than an hour. The insane resolution seemed to be more flashiness than function anyway.
