Dear Editor;<br /><br />As I said last week, I am sending one manuscript for your professional editing.<br /><br />Actually, this manuscript is 1st revised version we should submit by end of this week.<br /><br />Two reviewers among four raised English writing problems in the original manuscript as follows:<br /><br />- "I had a difficult time reading through the manuscript. Some improvement of the English would be necessary to make the paper more readable." <br />- "The present use of the English language is inadequate for a journal publication."<br /><br />Could you check it thoroughly to overcome this harsh comments? Particularly, red colored<br /><br />statements were revised ones. Please have more attention on them.<br /><br />After your editing is done, could you provide any letter or certificate to submit as a proof of your professional service to reviewers?<br /><br /><br />Your quick and professional editing service are always awesome.  <br /><br /><br />Best wishes,<br /><br /><br />Sung C.
