I am new here. I am also a professional programmer (and a teacher, parent) who wants to better understand competitive programming in general and USACO in particular.
Thank you for your effort. This is really remarkable! I will try to contribute as much as I can (and, in the process, I hope, I shall become a better (competitive) programmer myself).
My first question is about the “Edit this page” link on the USACO guide. I created my Login, however, when I want to make some minor modifications (like, for example, missing punctuation or typos) I get the above error from the editor. Do I need to do something else to be able to submit my edits?
