I'm not sure about the rep thing. I've seen deleted answers in the past, possibly because I've got mentor status, but I vaguely recall someone saying that higher-rep can see them (hence the IIRC in my reply).
I think that if you use "Improve Answer", the answer will be edited, but still deleted. Once, I posted an answer and deleted it accidentally. I used the "Improve Answer" button to edit it, but after editing my answer, the answer was still deleted.
In some cases, my signature will be longer than my message...
If you can edit, you can get the text with the html-tags and other stuff you have added into clipboard, and then paste it into another answer.
Without the editing function, then you can only copy the result as they are shown.

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpfull answers is nice, but saying thanks can be even nicer.
