If you're new to the site and you're waiting for your MineSquish application to be processed, we have another server that you can join in the meantime:
There's no application for Chunk Error - just visit the page above, read about the server, and click the button at the bottom of the page. Enter your MineCraft username into the form (make sure you've typed it correctly!) and that's it - you're whitelisted on Chunk Error!
Chunk Error is a unique server where every player gets to have up to three of their own worlds that they completely own. The Chunk Error support and help forums are here -> http://indiesquish.com/community/viewforum.php?f=31 and you can type /help in-game for a list of commands available to create and modify your world settings.
