I just posted a different question, backspaced a lot to reduce character usage, but accidentally left a gramatically incorrect word in. I'm terrible at both organization and typing... Can I change the wording of a question once it's posted?
The "edit" option on an answer allows you to edit your answer at any time. Note that until you have enough points, it will have to be manually approved by a staff member every time.
I recommend reading some questions in our starter guide to understand what you can do on this site.
