Situation: This is a message I want to post to a group of 20 people mentioning:
Anyone free tomorrow, let's plan to meet. name-1, name-2 and name-3 are in.
Does using the words "are in" here is correct? The intention is to convey that name-1, name-2 and name-3 people are coming to meet together, so if others wanna join, they can come too. Is this correct English? Any alternate ways of saying the same?
