It can sometimes be difficult to find a server that you like. The "random join" option only works if someone is online when you are looking, and doesn't catch Mac servers.

This thread organizes most active forum servers into categories so that you can easily find ones you are interested in. I've also organized the servers based on Survival / Custom rules and based on a few custom rules. Enjoy! If you think I missed something obvious, or I made a mistake, please let me know! (I'd kind of like to add some more server themes, as a few servers didn't really fit into any category perfectly)

Note: Servers were chosen by looking at threads in #multiplayer that have >10 replies and have been active within a month. If I missed a server that you'd like added, let me know! I've skipped servers which don't have a substantive OP as I didn't have time to join all the servers to get a feel for their theme. Servers by banned users have not been included.

### Servers by theme

${Array.from(themes)
    .map(theme => serversBy(byTheme(theme), theme))
    .join("\n")}

### Expert servers

${serversBy(s => s.expert)}

### Custom servers

${serversBy(s => s.type === "Custom")}

### Survival servers

${serversBy(s => s.type === "Survival")}

### Cloud servers

${serversBy(s => s.host === "cloud")}

### Mac servers

${serversBy(s => s.host === "mac")}

### Servers with PVP on

${serversBy(s => s.rules.pvp === "on")}

### Servers with PVP off

${serversBy(s => s.rules.pvp === "off")}

### Servers by size

${["1/16x", "1/4x", "1x", "4x", "16x"]
    .map(size => serversBy(s => s.rules.size === size, size))
    .join("\n")}

### Servers by TP rules

${Array.from(tpRules)
    .map(rule =>
        serversBy(s => s.rules["trade portals"] === rule, formatTitle(rule))
    )
    .join("\n")}

### All servers

${serversBy(() => true)}
