When emailing a group how do I edit the group addresses for that email only?

For example if I get an email from a group member and I want to forward it to the rest of the group but not the group member I just received it from, how do I do that?

i don't believe you would have that option. You could post it as a special notice so more members would receive it but that would also include the member who sent it to you. Ordinary members cannot use the special notice option.
