You can create the chat channel for your own
I know, but it is not permanent. After everyone in there logs out, the channel has to be re-created and a lot of people don't want to manually join the channel everytime, so the chat becomes quickly useless.
I am writing this suggestion because I remember that, a while ago, a permanent French channel was created. I don't know if this is still functioning or not, but I think that permanent channels for the major languages are useful, mostly in order to give assistance for new players that spam in chat in their own language forcing the admins to say every two seconds "only English in chat". Having languages permanent chats could be helpful.
