<P> The issue is also shown in the film Trekkies 2, in which a Star Trek fan recounts a supposed incident during a Star Trek convention where Gene Roddenberry used the term "trekkies" to describe fans of the show, only to be corrected by a fan that stood up and yelled "Trekkers!" Gene Roddenberry responded with "No, it's' Trekkies .' I should know--I invented the thing ." </P> <P> Star Trek fans who hold Star Trek: Deep Space Nine to be the best series of the franchise adopted the title of "Niner" following the episode "Take Me Out to the Holosuite", in which Captain Benjamin Sisko formed a baseball team called "The Niners". </P> <P> There are many Star Trek fan clubs, among the largest being STARFLEET International and the International Federation of Trekkers . Some Trekkies regularly attend Star Trek conventions (called "cons"). In 2003, STARFLEET was the world's largest Star Trek fan club; as of January 1, 2011, it claimed to have 4,145 members in 228 chapters around the world . Eighteen people have served as president of the association since 1975 . Upon election, the president is promoted to the fictional rank of Fleet Admiral and is referred to as the "Commander, Starfleet". Since 2004, the president has served a term of three years . Wayne Killough became the association's president on January 1, 2014 . April 17, 2016 marked the first time a Commander, Starfleet died while in office . The late Wayne Killough was succeeded by Robin Woodell - Vitasek . As of January 1, 2017 Robert Westfall became the President of the association . </P> <P> There is a persistent stereotype that amongst Trekkies there are many speakers of the constructed Klingon language . The reality is less clear - cut, as some of its most fluent speakers are more language aficionados than people obsessed with Star Trek . Most Trekkies have no more than a basic vocabulary of Klingon, perhaps consisting of a few common words heard innumerable times over the series, while not having much knowledge of Klingon's syntax or precise phonetics . </P>
