How do I start detective team?

To start your own team, you'll need 5000 coins. Enter the lounge and click on the people icon, bottom left. It will show a list of current teams but there should be a button to start your own. You'll have to decide when you want club coffee time. In the description, be sure to explain your expectations (i.e daily coffee only, competitions only, both, neither, chats or no, your time zone only, etc.). Then decide if you want an open club (anyone can join, no need for approval) or application club (you or an officer must approve before a player can join). After club is set up, you'll need to find players. You can use the in-game invitation to invite those on your boat list. Otherwise, find players on FB groups. If your club is an application only, be sure to check the in-box periodically, since the game will not notify you if players have applied and await your approval. Making a team takes some effort and trial and error. Good luck.
