Jebbiez:
I wanna edit the profile of a singer/entertainer, just like the example you gave above, to add on shows that were featured in. But I couldn’t find any edit button on the page, so I created my own list
I believe you can go to the shows they were on,
so https://mydramalist.com/25919-radio-star
Then ‘edit this page [button]’ > ‘cast [button]’ > scroll down the list, ‘search to add cast member [search field]’ > choose role etc [drop down button]> in additional notes the text box below, it’s best to insert your source, give explanation> ‘submit [button]’ > wait for staff’s approval
Just check/make sure the data is actually missing before you edit. Also if they reject the edit you will get a message, if they accept you won’t get a message.
