well if anyone who wants to be apart even if u invite them they have to show everyone else in clan that they are welling to be apart of the forum,
because if its just a battle buddy and doesn't get on the forum at all or just a little we can just add him to the ally list..
because we are trying to create a community here in [MFR] not just expansion..

so to answer ur question yes i think anyone like that needs to at least post something regarding that he wants to be apart so we all can get to know him too...
