I was thinking that we have a lot of planned projects that may or may not happen. I made a topic specificly to keep track of projects so we can keep note of what they are (this topic is for large projects that are server wide and not personal projects).
A hopper mail system, Monkey Mad and I thought of a hopper mail system that can carry items from spawn right into their player bases vice versa. We have enough iron to make the hoppers but I am not sure if the server will lag because of this.
The mail system will only be connected to active player bases, the farther away a base the longer the item will get there. Also the hoppers can move items through unloaded chunks.
