You don’t have to play if you join Tribes. You won’t notice any difference when you play the other games. By accepting, you are really helping that person. They have to invite you. There are big Missions that I miss out on because I need 2 more members. It’s frustrating when people don’t understand this..
I am sorry that I have not been able to play every day but I have been taking care of my husband he has been in the hospital and very sick and he is home now but has to have a lot of care so I will play when I can , you all have a great day
