On our Rules page, the gist of Master Ubar Papa's post has now been condensed into a general-purpose rule which states:
"Cliques are not appreciated, nor will they be tolerated. Close friendships are treasured in MTC... but so are family ties and unity. Although one-on-one role-play will sometimes occur, especially when Clan business is involved, do make it a point to interact with all of the members of our home. Our family grows larger each day, and each member has something to offer; please be sure that no one ends up feeling alone in a crowd. On the flipside to all of this.... do understand that if you are the type of person who waits for a personal invitation to join in, you may well be waiting for quite some time. We are naught a home of meek, timid, and shy people. We are Tuchuks. Step up and join in!"
