So how does this work? I see the same thing going on the #Balkan thread as happens here, with the local community making noise and a show of hands in hope to get their channel. Personally I would suggest changing how the in-game channel system works to allow creating and joining custom channels, this would allow communities to form themselves without the need of mods intervening. Alternatively just create a 'language' category within the main channel list that expands into the dozens and dozens of different languages so that users can find the channel suited for them. Ideally allow users to enable auto-join to their favorite channel whenever Osu! loads up.
I realize Peppy is very busy and that these things take time to implement. Until the chat system can be looked at, can we have the few extra language specific channels we are asking for on forum added? Should only take a minute to do so. The communities can be happy, spammage on forum is kept to a minimum, in-game activity rises, everyone is happy. Win-win, surely.
