Edit Function and delete function for original post

It would be very helpful if the original person who posted something could edit or delete it. Case in point, I misspelled Geir's name in an original post and did not realize it until I hit the button. So, I had to reply rather than simply edit. Yes, I should have been more careful and I will try to be moe careful in the future. But given that we can edit replies, I wonder why not original posts so long as it is the person who originated the post.?
