Any chance a short grace period could be implemented for editing one's own posts without incurring a line at the bottom of the post saying 'This post was modified...'? I think 5 minutes should be enough for those of us who often post, re-read, then edit our posts should be enough. 

I'm the kind of person who nearly always spots a typo or wants to clarify a point right after I've posted something, but getting that message on the bottom of all my posts puts me off doing so.

Thanks

Look - I've edited this post right away to show what I mean - this message below here:
