I do not want to say something as a straight halacha which someone who trusts me may rely upon in a way which was never meant.
Most reasonable people shouldn't take DDF posts, even from a distinguished member such as yourself, as a Halachic ruling.
I see it like Lubavitchers getting smicha before getting married, it's not in order to be a Rabbi, it's in order to have a proper awareness and to know how to ask a שאלה.
