Install a Pinehaven's 100 Days Winter Horse Rescue server through the Control Panel (Servers → Select your server → Game servers → Add Game Server → Pinehaven's 100 Days Winter Horse Rescue)
Great server overall. Setup was quick and easy, and everything runs smoothly with minimal lag. The control panel is simple to use, even for beginners. Support is decent and responds in a reasonable time. Would recommend for anyone hosting a Minecraft server.
