Merging two accounts or the lists of two accounts

Hello, @Jon, Thanks a lot for your response. I understand about the merging of accounts. But just to be sure: there is no way to merge two lists or to upload a list from one account into another one?

Thanks a lot @Col_Needham Indeed, the FAQ explains how to copy a list within one account. I still don't see how I can access from my account a public list created by another account and copy it in my account. As far as I know this is not explained in the FAQ. Can you explain how to do it? (I am not IMDBpro by the way). Thanks in advance.

@Col_Needham So I found the list I want on IMDB.com. I copied it. Then I registered to my account and tried to copy the list in another list I created there. But nothing happened or it did not work. What am I missing?

Thanks @Col_Needham It worked for 2 lists: when I did "copy to" the lists on my other account appeared... (why those of my other account and not yours for example is still not clear to me). But then I was not able to do it for the third one... without any explication... so I did it manually since it was a short list. So the case is solved for me and I thank you again. I believe your explanations here above should be included in the FAQ list. Have a nice day.
