If your friends play different games across different servers, finding someone to actually play with on any given night involves a lot of pinging and waiting. Most LFG solutions are either tied to a single server or require you to join yet another community just to find a match.
LunaLink was built around a different idea: what if one bot could sit in all your servers at once, build a shared pool of available players, and let anyone search that whole pool with a single command?
The cross-server search means that when you run /findparty, you're not limited to whoever happens to be in the same server you're in right now. You're searching the full network of servers LunaLink is active in.
The DM relay solves the communication side without requiring a shared server. Once your party forms, the bot becomes the relay point. Everyone talks through their DMs with LunaLink, and messages are forwarded to the whole party. No server invites. No sharing personal contact details. Just coordination.
The goal was to make the whole process — from "I want to play something" to "I'm in a party with people" — as short as possible. A couple of commands and you're done.
