As yet another semi-frequent contributor to this group I'd like to
point out the following option that I often exercise. When I answer a
question by a Mathematica user who appears to need the answer quickly
I simply CC the answer to him or her as well. Then, independent of
the Moderation, the (hopefully) useful content of what I have to say
gets to the questioner promptly and is shared more universally when it
appears in the group...
