I'd disagree on three accounts...
a) there are innumerable user-written ado's that are not covered in
the manuals.
b) help is often solicited for the most appropriate method of
analysis/availability of statistical procedures within Stata.
c) bugs in programs are often reported and fixed through the list.

The question you asked (How can I draw a bell curve (the density
function of standard normal) in stata), was answered by Nick's
original response, as it is documented in the graphics manual how
to do this.

If you were seeking advice on a more efficent way of achieving what
you had already coded then thats the question you should have
asked (and you should have included the code in the original post).
I've used Statalist and various other mailing lists/newsgroups for
some time now in soliciting help with problems ranging from
statistics, stata, and linux admin. I don't post often, but learn a lot
from reading other people's solutions to postings. A lot of people
(myself included) when they first start posting pose a question
which they think is reasonable, and then get
annoyed/offended/frustrated when they don't get the explicit answer
they require. This is because if you want a specific answer you
have to ask a specific question.
There is advise on mailing list etiquette in general at http://list-
etiquette.com/ (and also other sites listed in
http://directory.google.com/Top/Computers/Internet/Etiquette/?tc=1)
but the Stata FAQ should also be read (see bottom of email for
URL).
