We have no set age limit for moderator, and we would consider someone of any age if they were the right person, but I would say as a guide around 12 and above. Also the IP is - mineblockz.com:25919 - but the server is on whitelist as it's under development.
We haven't set a specific date yet, but we are hoping it will be in a couple of weeks. If you apply for Staff you will be part our team creating the server ready for the release and have a huge input into decisions. You will also have the opportunity to help build.
Or if you want, you can apply, and wait until we release in a couple of weeks before you start helping as staff
