Every group has a chat room. However only the admins and group owner's can open it. If you want to chat in a specific group then message the admin team of that group. There are several "chat" group with rooms running 24/7 and they have several topic rooms going inside the main room. In the search field at the right top corner, type in chat and you'll a bunch of them come up.
