Dear authors,

Thank you for your responses, but unfortunately neither of the two reviewers nor myself are satisfied with the answers yet. It is really critical to receive a thorough proofreading from a native English speaker, and this applies for both the manuscript and the actual replies to reviewers. There are parts of the replies to reviewers that are nearly impossible to understand, not to mention that some replies sound like the questions were not properly understood from your side and you are answering something different.

I would like to ask you to resubmit your replies, corrected for English, and also fix the manuscript to the appropriate level it deserves. In addition, when resubmitting your reply, please pay close attention to the comment of one of the reviewers: it is not sufficient to reply in the answers document. A reader might have the same question as the reviewers. For each reviewer question, as appropriate, you need to state your reply, how you changed the manuscript to reflect that reply (as needed), and a quote of the updated text.

Last but not least, do not forget to reply to the couple new comments of reviewer #2.

Thank you very much in advance,
Kostas Tsigaridis
