Definitely advise you to build your lists here https://www.mangaupdates.com/ It's made specifically for listing manga/manhwa/manhua, has an extensive amount of entries in it's database that are usually up-to-date thanks to both active mods and members, AND it even has doujinshi of anime/manga that aren't listed on other list sites like MyAnimeList, AniList and Kitsu!!! It's very useful, and if you just copy-paste the names of the stuff you've read into the lists, it shouldn't take you over an hour to do ^^
Thank you!! Hope nothing's goes wrong with site still though (￣ε(#￣)Σ
Omg!!! I was so stressed, do ya think is going to happen again??
I'm gonna save screenshots of my bookmarks and want to read, I'm reading mangas just in case.. but, do you have pages to recommend that are as good as this one? (￣∇￣")
