editing guidelines for Unix SE

Question

So you guys have granted me enough rep to edit. :D

But before I dig into people's questions/answers, what conventions/rules/guidelines should be followed when editing?

Answer 1

Obviously we can come up with our own policies, but this has been discussed on the main meta quite a bit, so that's probably a good place to start; What is the etiquette for modifying posts? is particularly helpful. There's also a blog entry on it

Answer 2

Up to this point I have only considered doing the following, all of which I feel are within the etiquette of this site:

• Tags
• Poor Formatting (ie, properly formatting code)
• Edits to commands that are either obviously wrong or corrected in the comments. (for example, find -type -f to find -type f)
• Adding/fixing links (especially since new users have a limit on the links they can post).

I think the following could be appropriate, but would like to see what others think:

• Fixing the grammar of posts written by users who are not very fluent in English. I don't mean fixing every grammar/spelling mistake (I have certainly made many), but simply making questions readable if they are good questions simply written by someone who doesn't speak English well.
• Putting Warnings on code that could be especially harmful.
• Adding a small amount of information to an otherwise excellent post. Often someone has 90% of the answer and I only see the need to point one small thing out. I often post this as a comment, but sometimes it would be nice to have it as part of the answer.
