No Thanks Share button for posts

[Dadparvar]

Hi,

Just for the posts that are "Public", a "Share" Button would be awesome. (Next to Like or Comment button)

What will be its usage? When a user click on the Share button of a post, and overlay comes and the user can choose one of these options (or both of them):

• Share On profile page
• Share on other group

When Done, then the post will be shared and a link to original post will be at the end of the shared post.
Exactly what Share button does in facebook:

• We will see a "X share Y post..." on top of shared post.
• X can't edit Y's post that is shared
• Comments below X's post (the post that is posted after X shared Y's post) will be displayed below the original post
• and ...

Thanks in advance
