Problems between sync of IMDb and Facebook accounts

I'm going to assume fok = Facebook.

If so, you are getting two things mixed up:

* Log into IMDB with your main account - this will show your lists, etc.

* You post comments to your lists using your Facebook login.

The comments section is run through the FB social media plugin, so should be considered an small island of FB within the IMDB page - to comment there you need to be logged into FB, to use IMDB you need to be logged in with whichever account you usually use (which for people who've been here a while is the standard IMDB one).

Sounds like you have two accounts: an IMDb.com registration and a Facebook account. If those two are registered with different emails addresses, then they are basically separate/distinct accounts so what you do with one will not affect or be connected with what you do with the other.

You do _not_ need to log into IMDb using a Facebook account in order to use Facebook-based features as long as you _have_ a Facebook account. The Facebook features are controlled by Facebook and hosted on their platform so as long as you have a Facebook account/cookie that you can use to log into them, you should be fine.

Also note that the 2 accounts don't necessarily need to be separate. If you had used the same email address on both, or if you had connected the two accounts (e.g. logged into your IMDb.com account and then connected it to the Facebook one) you'd only have one registration. I think the problem occurred because you already had an IMDb.com account but at some point _logged_ into IMDb using Facebook. Since your Facebook account is probably registered with a different email address than the one you used for IMDb, this created a second IMDb.com account for you (linked to the email address you use on Facebook).

I don't understand this as well.

What did i have to do now?
