去年10月份投了篇国外期刊，改了几次后接受了，但是回信内容看不太懂，请教！

  1.We have considered your paper and are pleased to accept your paper in its current form for publication in ****, subject to an originality check using the CrossCheck™ software.  Once the originality check is complete, the paper will be forwarded to the Production Editor for copy editing and typesetting。

请教：“an originality check using the CrossCheck™ software”什么意思？（是不是论文原创性检验啊？是不是有不通过的）
另外，“the paper will be forwarded to the Production Editor for copy editing and typesetting”应该和我没有关系吧。

  2.You will receive proofs for checking, and instructions for transfer of copyright in due course.
         The publisher also requests that proofs are checked and returned within 48 hours of receipt。

请教：“proofs for checking”是什么意思啊

   3.Please note, if you have provided a PDF file for the peer-review process, you will need to promptly supply your original source files when contacted by the publisher. These source files will prevent any delay in the copy editing and typesetting process and the eventual publication of your manuscript.

请教：是不是当publisher 联系我后再发给publisher，publisher是不是编辑部，还是？

4.Please visit www.******* to sign up to our free table of contents alerting service.
请教：这句是什么意思啊，英文水平太差了，没看明白呢。

英语水平太差了，又怕自己的理解不正确耽搁了时间，所以请教各位了，万分感谢！
