Well I figure we need ways to get our characters to be connected somehow, forge a bond between two people who know about each other who then bond with two more people and thus creating a chain of acquaintances until everyone's characters in the RP know each other, if not by directly meeting them then by word of mouth of their friends. Things like group projects and possible battle teams, you know maybe they'll promote a team tournament with a large number of people on each team depending on how large the academy is, as twelve to fourteen people on a team may or may not be considered too large depending on how many students attend, after all having a hundred teams of three or four or five would take forever, plus it would allow for interaction between people of various years, promoting balance and preventing a single team from being too overpowered like having all seniors on a single team... team that wins the tournament... I dunno, get to meet the Elite Four member of their choice or something grand?
