That could be a question or an answer depending on the tonality of the speaker.
1) Question : Hi, how's it going my brother?
2) If answer: Hi, my brother. I'm doing well.
But as the sentence started by salut , so it's normally a question.
Hello dsryr75. I'm sure it's a question. "ça va bien" can't be anything else. Of course it's a bit weird, no diacritics, and of course your English sentense is more beautiful , but we've just to say if the translation conveys the meaning and not to change it completely. SVP, surtout ne le prenez pas mal.Je m'exprime juste exactement comme vous/toi; Bienvenu sur notre cucumis. Ici c'est tout simplement génial. J'espère que vous allez vous y plaire.
