Hello once again, one thing that I kinda agree is that free male users can't do group, but a cool thing would be if a free user could be invited to join a group with 2 premium. Better explaining, if I want to do MFF and I'm premium, the other F is premium a free M could be invited, this could ba aplied to MMF cases: M premium, F premium, M free.
I think is a coll idea, this may also serve has an incentive for free users become premium.
Leave your opinion and have fun.
