"If you haven't noticed, I haven't had the server up for a while, and it'll probably stay that way through August. I have some cool ideas for the Battle Server and hopfully I can implement them before the fall. Unfortunatly I am rather busy now with school and our current game project to work on it at all. (Yes, I'm still in school for the summer.) Hopefully I'll find enough time to offer you guys (all two of you) something new in the fall. Till then, have fun with all the other servers that are up durring the summertime, not to mention going outside , and don't forget to upgrade to v1.24."
