I think there are some people who have not met each other before, so why don't we start with self-introductions and how things are going for us these days?
ご質問ありがとうございます。
"I think there are some people who have not met each other before,"=「お互いに会ったことのない人たちが居ると思います」
"so why don't we start with self-introductions"=「なので、自己紹介で始めませんか?」
"and how things are going for us these days?"=「そして私たちの近況について。」
ご参考に。
