Install a Simple Voice Chat & Proximity Chat Modpack server through the Control Panel (Servers → Select your server → Game servers → Add Game Server → Simple Voice Chat & Proximity Chat Modpack)
the server is easily accessible and rarely lags. as a server owner, i like the variety of settings and options i am given for my server. i like how the server stays up for as long as i want. the number of people who can join is generous in my opinion. overall really good experience!
