Editorials for all rounds starting from SRM 467 can be edited by any TopCoder member. It can be language correction, wording improvement or additional explanation in some parts, your additional comments, description of alternative solutions, etc. If you want to improve the wording of editorial writer or correct some language error, please feel free to put your change over the original text. And if you wish to add a comment or describe another approach, there's a section for this at the bottom of each problem.
If you see that you occasionally broken the page formatting, you can use page history page (like this) to restore the latest proper version. If you don't see how to do that, please contact admins (firstname.lastname@example.org).
