I've figured out replacements for some links in #583 (comment).
I've figured out replacements for some links in https://codeberg.org/forgejo/docs/issues/583#issuecomment-1802468.
- [[link]](https://github.com/go-gitea/gitea/blob/e865de1e9d65dc09797d165a51c8e705d2a86030/docs/content/help/support.en-us.md) `seek-help.en-us.md` was a website-only alias at that point of history. The right filename was `support.en-us.md`;
- [[link]](https://blog.gitea.com/release-of-1.11.3/) `release-of-1.11.3`: they seem to have renamed them.. and changed TLD. It's the same post;
- [[link]](https://github.com/go-gitea/gitea/blob/main/docs/content/usage/actions/faq.en-us.md) `actions/faq.en-us.md`: the dir structure was changed in 2023.
