You mean quadrotritichlorians, don't you? * Start by watching some episodes. (Where you start doesn't really matter all that much.) * If you enjoy them, try watching some more. * Repeat, as needed or desired. Try some episodes from another Trek series, or one of the movies. * You don't even need to worry about when to call yourself a Trekkie; I've been at this for quite a while, and I still just think of myself as someone who enjoys watching Star Trek. * If you feel like it, you can also talk about Trek stuff here with other people who like to talk about Trek.
