Um, I'm not really sure how I should update this series.
So Trump was actually a fan-work trying to get published in Naver and it even went through a total remake twice. The first time, the mangaka just restarted because she didn't like how confusing it was. Now, that Trump is finally actually "serialized" by Naver, she's starting over again. In Naver, when webcomics get "serialized" the authors have to start over their work from the beginning, sort of like how mangaka add things/redraw things in volume format for japanese manga.

So should I make another series info for Trump and link the other Trump thing as a related series or just rewrite over the old series info for Trump?

Here's the first try
Here's the second try
and here's the serialized version

The same thing happened to another series from Naver that's listed on MU. Unfortunately, I can't remember the name of the series. I guess you could just follow its precedence if someone could help with the name of the series

A just ruler amongst tyrants

I think you're talking about Crepuscule. But I'm not exactly sure how they differentiated the two. Did they just use one author's name for the previous one and the author's name for the other one? If so, should I just name the other one "Trump (Lee Chae Eun)" using the author's name and leave an explanation on the previous one and make it related to the new series info I'm going to make? The mangaka used her id sinceby1991 to first publish Trump when it was just a "bestcomic"

**edit: So I just went ahead and added Trump (Lee Chae Eun). I went back to the previous Trump to find the author's name sinceby1991 and requested it to be changed to her real name Lee Cae Eun. Now, I'm trying to add her id, sinceby1991, as an alternative name but I keep getting the "on maintenance sign". But other parts of the site are working fine...??
