I sometimes submit content on here with typos or overlooked details that should be added. However there is no way to edit my post or the editing UI is hidden or difficult to find. Most websites permit editing of content after it has been submitted. Sometimes editing is only permitted for a finite length of time after submittal (to prevent abuse) while other sites like facebook (for example) have no time limit. At the very least a user should be able to delete his own Idea for a limited window of time so that he may rewrite it and submit again.
