Yep and it is taken into account aswell and... for sure; if french-speaking chatters prefer another chat service without a minimum of professionalism, they're the only ones concerned (I'm talking about the FRENCH chat sites I know of course).. Buzzen is not that stupid; we know there will be a chatter loss but Buzzen will at least gain in credibility because it won't be an MSN-Clone anymore and I think everyone here agrees that the credibility is more important than the amount of chatters.
If they're not a lot to leave, well, that will be a good point but the debate ends here I guess
