okay, so I recently started to rent a VPS but cannot seem to get it functional and working. If anyone would possibly be able to help me set up some sort of plugins/server mod to link multiple servers together.

I have a multicraft Key for 5 servers but have no idea how to go forward from here.
If anyone could be of any assistance, I can make some sort of animated banner or link their own server to mine as sort of payment.

Hoping for a quick response! I need help!
