Pimping the
'Little Black Dress' Challenge on
gaeta-squee where we try and pair Gaeta with everybody who he hasn't been paired with before. You should check it out. Even if you're not a Gaeta fan, you could still write a fic centered on an interesting, underused character such as Laird, Crashdown, Gina or Seelix, with Gaeta staying in the background, looking pretty.
Also, I'd really like to read that story about Gaeta and his hand. Heh.
