I've just tried to edit your post, Major, and I find that I can. However, that may be because, as a Moderator, I have the ability to edit out offensive, potentially libellous or other unacceptable comments or words. Maybe Teflon can try to edit this post - not this post =quoted, and report back?
Thinking back, the old forum allowed quote editing which was useful if you wanted to highlight just one sentence out of many.
On the other hand, I also think that quotes should be verbatim otherwise it would be possible to misrepresent something said in a discussion by changing some of the text.
A conundrum, methinks!
