I wonder if it is possible to delete one's own posting from the community site.
In the past, I've wished to delete one of my own posts for two different reasons.
1) I have posted something completely stupid, and I want to remove it.
2) I've posted something and then hit my browser's back button. This brought back active editor with my post, and not thinking that I've posted, I hit "publish" again. The result is a duplicate post.
