Slash apas

An Amateur Press Association or APA is a group of people who produce individual pages or magazines that are sent to a Central Mailer for collation and distribution to all members of the group.

Terra Nostra Underground

The Terra Nostra Underground (TNU) was founded in the fall of 1989 as a quarterly apa for discussion among slash fans; it began with eight members, and its membership had reached twenty-three when it folded in summer 1993.

Strange Bedfellows

Strange Bedfellows (SBF) was founded as a successor to the TNU, and at its peak its membership was 37. It folded in summer 1998, largely due to the impact of the Internet on slash fandom.
