i use to be apart of one when i was in highschool, then i eventually took it over when i was a senior, basically it was always run by seniors cause they already knew teachers that would let us use their room for the year, every wednsday, and most rooms already have a big tv/dvd/computer hook up, so we just put xvid on the pc and we watched all new anime that came out, or full series like please save my earth, rayearth magic knights, like switch it up between movies, series, or just show like 2 episodes and see if people want to watch the rest, but we never watched anything that had already been showed on cartoon network , cause like whats the point of showing anime that people can go see at home.
ohh and it wasnt called just anime club, our school wouldnt let that fly we had to have some sort of educational experience to it, so it was called the japanese culture and anime club(and then we called it genshiken..jk^^), and at the start of the meeting just say some fact about japan that most people aready knew, and we did have manga days and days people would bring in japanese food~!it was awsome. iono hope this helps somewhat, and goodluck~!
