Slash apas
A number of APAs dedicated to slash have exited over the years. 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.
