I'm fairly good with commands and command blocks... I've started several successful servers that I've only stopped because I've ran out of time. I'm also good with worldedit, if that matters.

Hey Manny! You can call me Luna. I have been an admin on several realms and have lots of experience with command blocks. I would love to be a part of helping you build your realm. I can even build some pretty awesome clan bases if you'd like. Please PM me!

i dont know much but here are the things i know

auto chat: This one is very easy and very simple to do. all you need to do is place a command block under the floor and place a block on top of that and a pressure plate on top of that so all you see is a pressure plate. and enter this text into the command block: /say @p your message here

weather Machine: enter the text '/toggledownfall' into the command block without the '' and place a block next to that command block and a button on that block and it will change the weather at your command

plans grow fast: /instantplant

giants: "/spawn giant (mob here)
