This is just for your sake before people leave bad review/messages on how your server works badly. If you do not act mature, nice, kind, caring, etc. Also, developer if there not paid should and shall not listen to what you \say about a plugin they make unless you pay them. And you should not be younger than the ages you list for applications. I also recommend getting a website if you want forums, buycraft, etc. If you do not understand anything that you should. And just for a final tip please have common sense.
This is advice I'm just saying this cause' these are my thoughts on people just posting servers without having these basic tips.
