So how much overlap will your level archive have with knyttlevels? I see, for example, that Dark Sky of Wish Mountain and Outsider are not on knyttlevels. (Unless there's been some title/author munging somewhere.)
Also, you say this is just your favorites. Will you be using different grades of favor, ex. "ego", "ego+", "ego++", etc.? (A couple hundred is an awful lot of favorites...)
Also also, while you might not happen to have any of these (https://nifflas.lpchip.nl/index.php?topic=6782.0) levels, you don't suppose you could crosscheck your mental list of "levels I'm pretty sure I got off mediafire or whatever" with "levels I'm pretty sure aren't on knyttlevels"? (after "infringing levels" and "way too big levels" of course.)
It's spurred, not spurned. Unless you're saying that your revamp was shoved away by and from that particular deletion.
