If you don't basically it's a site where you can keep track of which anime and manga you are reading and which ones you have completed.

You can also make a list of 'favorite' anime/manga/characters/people. With a limit of 5 anime, 5 manga, 10 characters, and 7 people

Sounds like something that I could make on Microsoft Word. Without the limits. I don't but I could. So no I don't have one.

Yes, and updating it regularly
