- contains a letter by [J C] commenting on the high cost of fanzines (they averaged $2-$10 at the time). This set off a long discussion in later issues.
- Boldly Writing notes that there were letters in this issue, and others, which responded to [D H]'s "remark that fanzine writers needed to put science fiction back into Star Trek, especially his implication that the reason that Star Trek fanzines no longer concentrated on science fiction was that their editors were largely women (women science fiction fans took exception to this). Those recently discovering fanzines seemed unaware of the fact that when fanzine stories were mostly science fiction, fanzine writers and editors WERE mostly women."

- Leslie Fish responds to Barbara Gordon's letter about TPTB's apparent obliviousness to fans, saying "The official ST novels are bad because they're farmed out to the company's stable of ... writers; outsiders (such as fans) are not invited."
- more on the Star Trek vs science fiction debate: one fan writes that she, "fell in love with the idea of ST, not the characters.... I couldn't care less if every last one of the regulars got transferred off the Enterprise as long as the Federation and its ships continue to explore space and take me along for the ride." Another fan disagrees, saying, "Star Trek IS Kirk, Spock and McCoy." Another fan complains, saying that "ST fandom failed to live up to the ideal of space exploration presented in the 1960s because they got hung up on the Big Three characters... Why not admit the possibility we could have done better if we hadn't held the spotlight so firmly on Kirk, Spock and McCoy."
- a fan has heard a rumor that Paramount is "going to kill off Spock." They rally.

- a fan suggests that perhaps Vulcans use the arts as an outlet for the emotions they have, but suppress.
- a fan, upset about the rumor of Spock's death, suggests they organize a fund and take out full-page ads in trade papers promising to boycott the movie. The November issue notes such an ad was placed in "The Hollywood Reporter." This ad ended up generating a story on the front page of the October 9, 1981 "Wall Street Journal."

- it contains a comment by Judith Gran about zines: "Maybe we should try to find reasons why ST fan fiction has changed, if it's changed.... I can think of a few possible reasons: 1)...a) The number of aspiring professional writers in ST fandom has decreased. Some of the best fan fiction has always come from fans who were practicing for a professional career as SF writers. Of course, aspiring professionals can't be expected to stay in fandom forever. In the last few years, many of these writers have left ST writing.... Some have gone pro, others have gone to other fandoms. And for the most part, they're not being replaced. b) ST fans are probably chronologically older.... Most of us, when we start pushing 30 or so, find our lives become busier, more complex, more full of mundane responsibilities. Unless you're a truly serious writer, it's hard to find the time and concentration away from career commitments and juggling complicated schedules to write complex, thought- provoking, well-crafted SF. It's (perhaps) relatively easier to dash off a story that's mostly 'feeling' rather than plot."
