You can start a conversation in the Cobu app within the Chat tab. The Chat tab can be used to post building-wide questions, ask for local dining recommendations, post updates, share gathering photos, etc. The more conversations the better!
You can also start conversations in Groups. When you join a group, you can press the "Discussions" tab at the top of your screen to start a group chat with everyone in your group.
After joining a group and then RSVPing or creating a gathering, you can start a conversation via comments! Write and post comments with gathering- and group-related questions as to spark discussion.
