Are you gonna change the forum from a Tatu forum to a Russian music forum? What if Tatu hit the jackpot again, you're gonna change it again? So I'm voting "no" for now, I'd rather see the Russian forum incorporated into the Tatu forum rather than the other way round.
You'll have to change the whole forum structure to do that, from the layout to the content. If that's what you want, so be it
I'm gonna stick around cause I like this forum and its people, even though Russian music is not exactly my forte
