Awesome, I've added the names 'ruthytoothy' 'messyblob' and bluepenguins34' to the whitelist, all 3 should be able to connect to the server at mc.indiesquish.com now
RE. Terraria, I'm not 100% if the server is up at the moment, I can check and get back to you but no, you wouldn't need to do another application, if it's up you're free to join now as well.
If you have any questions, holler and we'll be happy to help!
