How to make new Title whose "Tracking Site" entry I don't have.

[Geako]

Hey, I want to make a new title. That title is fan made comics of author. This is doujin Hence it's entirely new work. So, there is no mention of it anywhere. I published it on Nico Nico on Fan Category, So, I got Raw Part figured.

Also, how to create data about myself as Author?

What should I do about "tracking site" info? It's not letting me to create without any one of such in draft.

Tracking sites have always been optional but maybe now they have changed that, in that case put a page that shows info for metadata purposes such as genre, creators and synopsis. If the doujinshi is a parody of an existing series/franchise it has to be formatted to fit the title standards. As for the name of the author/artist, in case it doesn't exist yet, once you type the name you'll see a blank space (meaning no results are returned) and a "+ Create" line, which means once it gets approved that name will be added to MangaDex database for future searches/tagging purposes.
In the Tutorial section there's even the style guide for doujinshi title names.

As stated before, tracking sites are optional.
I assume you're running into something like this?

That's just the frontend telling you that input validation of your link failed (because you didn't input anything). Just click the delete button on the right in that case/don't click the "add tracking site" button in the first place...
