Enlightened_Being I've done a couple of contracts and I'm not sure what all Webnovel asks for, but with websites like this, it's typically not full rights. If it is full rights, run. You never want to sell your copyright, film and television rights, non-digital publishing rights, etc. If they want rights to publish the story on their site that should be the only thing requested in the contract. There's possibility of the first right of refusal, but that shouldn't be a big issue for most. It's pretty standard in contracts these days. On that note, 50% is standard for digital one-website publishers. It's not a bad deal at all considering traditionally published books get half that or less.
