I should reiterate my warning that the Borg Plot Classification involves spoilage. All the stories listed below are either linked on my story index page or are works still in progress.
Plot 001: Court Martial - The return to the Alpha Quadrant is a mainstay of Voyager fan fiction. Once back, however, our lovebirds must deal with criminal prosecution and the risk of dissection. Related plot: 007.
Plot 002: The Episode Addition - The average Voyager episode doesn't contain nearly enough C/7 scenes. Fortunately, this flaw is easily corrected.
Plot 003: "Natural Law" Done Right - They must have left out a few monkeys and the bathtub. Fix up this disappointing C/7 episode.
Plot 004: The Talk - Seven tries to talk sense into Chakotay.
Plot 007: The Prison Break - We can't just let Chakotay rot in a jail cell, now can we? Related plot: 001.
Plot 009: The Unexpected Pregnancy - The title says it all.
Plot 013: And the Children Shall Lead - Naomi, Icheb and/or Miral voice their opinions on C/7.
Plot 015: Shore Leave - The search for the Risa of the Delta Quadrant. Related plot: 554.
Plot 020: Busted! - The crew find out about Chakotay and Seven's relationship.
Plot 023: The Borg - There's nothing like a few nanoprobes to make life interesting.
Plot 025: It's Prixin Again - Prixin is Neelix's answer to Christmas. Either holiday falls into this category.
Plot 026: The Ghost of C/7 Future
The characters haunt the fanfic writer until she writes a C/7 story. Also in this category: parting stories written by authors leaving C/7 or Voyager fandom. (Don't let the door hit you on the way out...)
Plot 033: Mirror, Mirror - The AU (alternate universe) plot.
Plot 051: The Stalled Turbolift - That says it all, doesn't it? Related plot: 052.

Plot 054: The Touch of Her Hand - Come on, give us some more finger-lickin' good scenes!
Plot 068: ABOTW (Alien Babe of the Week) - What will Seven do to keep Chakotay away from Species 8472, those blondes from fluidic space?

Plot 087: Passion on a PADD - A PADD story can go anywhere, fast. In triplicate.
Plot 100: The Drabble - A drabble is a story of exactly 100 words. Related plot: 101.
Plot 101: The Vignette - The vignette is similar to the drabble. Under this classification, the Borg include all short stories sans plot. Related plot: 100.
Plot 112: The Proposal - Man proposes, God disposes.
Plot 113: The Bonding - Is marriage irrelevant?
Plot 117: Home Soil - I guess this would mean C/7 going back to Dorvan.

Plot 518: Ferengi Love Songs - Songfic and filk.
