Can a user edit and then vote on a post originated from another user?
What is meta?
- Any Stack Exchange user can ask a question
- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates
As you edited a post created from somebody else, you are allowed to vote it. You cannot vote your own posts, but editing somebody else's post doesn't make the post yours.
Yes, user can vote for self-edited posts, but points belonging to the post go to the original owner.
