My suggestion is simple yet needed in my opinion, I accidentally just invited someone to my campaign while looking at their forum post on my LFG post. This happened because there is no confirmation after the invitation is sent and I´m not able to un-invite then either. So what I am asking for is simple a confirmation after you´ve pressed the Invite button or the ability to revoke inventions. Also yes I can kick them later, but only after they join and if they join the can disable my lissting if my player quvota fills up. So this is not a great way to deal with it.
