Leaders are charged with the responsibility of moderating G2G. Editing is part of this process. Here is what is written regarding editing:
Editing Questions
Keep in mind that G2G is not wiki, in the sense that editing and improving upon other people's work is not generally encouraged, carefully tracked, etc.
When you edit a question, a line will appear that says you edited it, but it will not say what you changed or why. Therefore, you should avoid making meaningful changes to what someone else wrote.
Please fix obvious typos and errors in the question itself, if it's safe to assume the person would want them changed. However, don't change the body of the question except in the cases below.
The Integrators Project is the place to bring attention to posts in need of editing.
