Sometime Today, SN cobbled together some glyphs to say:
by 'NOT' top posting you meant posting below the reply? Apologies, not used
I don't know what he meant, but NOT top posting does not mean put your reply below the original - at least not in all cases. You should put your reply interleaved with the original, and delete unnecessary parts of the original, leaving only what is necessary to maintain context.
search the web for top-posting for more details.
