At most universities (and many other places) there's a single group of "those weird people" that does science fiction, gaming, paganism, etc. MITSFS gets occasional email from people thinking we're that; actually, the relevant population at MIT is large enough to support separate groups. (Which tend to have lots of overlap, of course.) So, if you're from somewhere else and were looking for all the weirdos, here are the places you might have thought would all be the same as each other and us:

• MITSFS, the Science Fiction Society, runs the world's largest open-shelf collection of science fiction.
• The Assassins' Guild is the live-action role-playing group.
• The Strategic Gaming Society has a subgroup for tabletop role-playing (though most tabletop gaming isn't affiliated with any official group) and a subgroup for non-RPG tabletop games, chiefly wargames.
• The Pagan Students' Group supports and promotes awareness of various non-mainstream religions; the rituals often tend towards Wicca.
• SEDS (Students for the Exploration and Development of Space) has a chapter here.
• The Anime Club holds showings of and maintains a library of Japanese animation (anime).
• LSC is technically the Lecture Series Committee but nowadays is primarily known as the group that shows movies.
• Mitgaard is MIT's chapter of the Barony of Carolingia, in the Society for Creative Anachronism, which by virtue of being well-established globally isn't really expected to be the same group as the others, but close enough.

The above activities are all student-centered but open to non-students.
