Perhaps not an announcement on Turkish alone but a general reminder that there are more languages here now. Like a “You know we have -supported languages- but did you know we have these -beta languages-? Don’t forget we have voting over at Facebook for new ones to be added each month!” kind of thing.
@Imyirtseshem - We do something like this from time to time 
Yeah, it’s good because some people only check from time to time.
There are nearly fifty lessons on Turkish LingQ now,from beginner to advanced.I’ve shared on my own,and there will be someone else
who want to share lessons in the future
That is great and I am looking forward to doing them. Are there third party resources we can you as well, radio stations, podcasts etc.?
