XF 1.3 RSS Auto Poster

[HappyWorld]

What if the specified RSS item is already posted on the forum, will that same item posted again?
Or XF will check whether that item is already posted or not?

We will log the unique identifier for the entry within the feed. If we've already posted that entry, it will not be posted again.

Thank you, i've tested to press "import" link several times and a same item was not posted twice. Great feature
So what is the unique identifier? is it the post title?
