There is a central repository, mirrored and filtered through formatting and translation for various sister sites, for all the interdimensional fiction (and all the domestic fiction). Of course it will instantly filter out elsewhere, no one size fits all, but this is meant to cover 90% of cases for the first months while everyone else with more niche reading preferences catches up.
Allfic has a lot of different ways for metadata to attach to the fic. The author can add metadata; the submitter, if different, can add their own; readers can add metadata, either traceable to them (for public curation) or privately (for sorting things privately). It can download to nine different formats, there are hundreds of skins you can apply to the website, and it supports four different machine translation protocols and their mods.
People from other universes will find that their character sets are supported and the tag wranglers are on duty to try to wrestle their categorization into some sort of harmonious equivalence.
Submitters should be advised that neither Allfic nor the typical Green government has a rule against or an enforcement policy about preventing people from sharing stories or creating derivative works. The normal ways you profit from being an author, if you do, are ways of leveraging your ability to canonize things, such as by having a paid question-and-answer account (Allfic has built-in links to eight of those, and a custom fill-in for people who prefer a different one); voluntary donations; and having a "fallback fund" - which doesn't pay you anything at all, as long as you're doing financially all right, but will kick in if you fall on hard times, with everyone who agrees that it would be pretty fucked up if the author who wrote that one thing were unable to make rent chipping in a little. Green is happy to trade fiction for fiction - since they don't have a rule against sharing stories, they can hand over everything they've got, and are prepared to construe this as a trade if that makes the aliens more comfortable. Money is not happening unless you somehow manage to convince someone to pay you for your work sight unseen.
