We've already started a long time ago. Although we appreciate you taking initiative, creating an adventure map is going to be handled by staff, when spawn is finished we will let all of you know of what you can do to help under admin supervision.
For now, be patient and hold your ideas until further notice. If you are eager to share them I will gladly read what you have to say, just send me a PM here on forums.
We are reading what you're writing on here, just because we aren't answering does not mean we are not interested in your experience.
