OnLine English quality guarantee

The English of documents edited by OnLine English will meet the standards of publishers and journal reviewers.

If you receive negative comments from a publisher about the English language of your OnLine English-revised document, we will:

answer any questions you may have about the comments that you have received from the publisher; and
check, discuss and revise any changes that you have made to the English language of the document in response to the comments.

There is no additional fee for this service, subject to the following conditions.

Conditions

The guarantee applies once you have paid for the OnLine English service.

The guarantee applies only to comments on the English language of the document. It does not apply to comments on the academic or intellectual content of the document; this remains your responsibility.

If you make changes to an OnLine English-revised document, you must ask us to check those changes. We cannot be responsible for a document where you have made changes that we have not checked.

If we are requested to edit only parts of a document, then the guarantee applies only to those parts, as we cannot be responsible for parts that we have not edited.

The guarantee does not apply to documents that are very poorly written; i.e., where we have notified you of the need for heavy-editing surcharges.
