If I understand your question, you would like to have distinct replies to each point somebody made in a statement. Since everything in between the [qu0te][/qu0te] tags is going to show up in a box, if you want something like this-
[qu0te]My comment #1[/qu0te]
Your answer #1
[qu0te]My comment #2[/qu0te]
Your answer #2
-what I end up doing is copying the entire comment block, and pasting it into my reply once for each individual point I am going to reply to. Then I just delete out the extraneous bits from each section. This seems faster to me than going in and adding the extra [qu0te][/qu0te] tags in the original text to make room for your comments.
