I've been thinkg about this for some time now,
But a discovery page in the multiplayer tab would be cool right?
It would have all the active servers from ServerMapping on it,
with their tags, language and other filtrations. And then a simple and quick "Add to server list" what will add it to your multiplayer server list for you.
This would boost the the ServerMappings servers playerbase by alot I think,
and also good for lunarclient; more players find a server to play and use LunarClient on since the server most likley uses Apollo.
