Sounds like a question for a lawyer in your country! As far as I know, if it's a question of first publishing on a fanfic site, pulling from that site, and asking readers to pay on your own site, that's all according to your rights as the owner. (As long as the fanfic site doesn't have any dodgy 'we now own your stories' terms of service bits.) If it's a question of professionally publishing fanfic with a third party, then that third party may object to the past free publication. (The publisher of *shudder* 50 Shades did not.)
The Word of Yuletide is this: the nominations process collects a list of rare fandoms that people are interested in writing or reading, and later comes the official participation signups. The signup means offering to write several fandoms and making several specific requests for fandoms. Then, offers and requests are matched - participants are given someone's set of requests and asked to write them 1 story, since at least one of the requests will be in a fandom they offered. The story must be complete, at least 1000 words, and include particular characters if they asked for particular characters. The stories are submitted in late December, revealed on the 25th, and everyone stays anonymous until January 1st.
In the Oz example, you might offer to write, "Oz - I'm willing to write General Jinjur, Ozma, and and Toto", and get matched with someone who asks, "Oz - please write about Ozma, I love friendship, genderbending, and adventure". Then you'd write a story based on that prompt but with plenty of latitude. Multiply that times four offers and requests, with a spin of a random wheel for which offer and request you end up writing/receiving. (For the record, Wizard of Oz *and* Ozma are available this year to offer and request, or at least ninety-nine percent likely to be! So is Lady Audley's Secret. And about two thousand more (https://docs.google.com/spreadsheet/ccc?key=0Ao3S2FvjegSNdDN5SklScTgzQ243WlVTZGpRRDhuTlE#gid=0).)
Because I'm a small fandom fan the rest of the year as well, I love Yuletide. :D The gift exchange part of it makes me happy; you write a story for someone else's dream rare fandom with not nearly enough fic in it, and receive a fic written in one of your own rare fandoms. Plus, there's no limit on extra stories you can write for other people. It's good if you want the challenge or fun of writing specifically for someone, and it's also got a large audience of readers.
