Thank you! A quick follow-up from that - I'm curious, did you get much warning about the removal from AO3? What was that process like?
Really, the mods were very gracious. I got about two weeks' notice before the fic was hidden (just hidden, not removed) in which time I was allowed to make changes to it. If at the end of the two weeks the mods didn't deem the changes sufficient, it would be hidden, and I'd be given a month to remove any offending content before it would have to be removed wholly. I took those initial two weeks to revise a couple of chapters I knew to be particularly close to the canon, in not just the content but the wording, and waited to hear from the mods if those chapters were good to go. If they were, then I knew I could revise the rest of the fic to comply with AO3's standards. Unfortunately, they still weren't acceptable, so while I took the rest of the time allotted to continue to revise in an effort to get to a point it would be acceptable, in the end it just wasn't able to be done--too many scenes play out exactly the same as in canon, and there's only so much I could reasonably do in the time given. While the mods tried everything to give me the time I needed to make changes, offering to extend the month-long revision time, I ultimately decided the fic would not be the same fic if I changed it that much and allowed it to be removed, at which point I began working to revise it wholly.
I worked pretty much exclusively on the revision from the beginning of February to the beginning of May, as reddit posts wondering what had happened to the fic were beginning to pop up, so I was working doubletime to revise and send out epub versions of the original to those who wanted them.
All in all, though, the AO3 gang was as lenient as they could be with me, and they still gave me plenty of time to back up the lovely comments and notes in bookmarks people had left over the years.
And in the end, I'm left with a fic I like better.
Suffice it to say, though, the next time I get the urge to rewrite a canon book, I'll be more adventurous!
