What are comments?

Comments are temporary notes left on statements and answers. They cannot be edited, but privileged users and moderators can flag and delete them. Comments can be voted on, but votes do not affect reputation.

Who can comment?insert_link

Users with a reputation of at least 50 can post comments. In addition, the user who posted a statement can comment on the statement and all responses to it.

How do I add comments?insert_link

Under each statement and answer to which you have the right to comment you will see the link add a comment.

Comments support the Markdown syntax, but do not provide the formatting toolbar. Comments are also limited to 500 characters. We set these limitations to remind you that the comment system is not intended for long messages.

When to comment?insert_link

• When you want to suggest clarifications to the author or report errors in his or her message.
• When you want to leave other constructive feedback that can improve the message.
• When you want to add transient information, such as:
  • that the statement has changed and the answer deserves to be updated;
  • that there is a duplicate of the message.

When not to comment?insert_link

In some cases, your comments, although well-meaning, burden the page and distract the community without bringing any real benefits.

• Don't just comment with "thank you" or other compliments. Instead, upvote the message!
• Similarly, don't just comment with criticism or disapproval. Instead, downvote the message!
• Don't use the comment field to give a different answer. Instead, publish a new answer or edit / expand an existing one.
• Don't suggest minor corrections. Instead, make them yourself!
