Dear Hui Wang, dear All:

I am extremely glad that the youngest among you find expert advice on  
this forum about such basic issues as discussed in this thread. You  
should be advised, though, that the human resources of the QE  
developers' team are extremely limited, and none of them gets any  
rewards for the their work other than the knowledge thay they are  
providing a (great) service to the community.

You will have noticed that most of feedback comes from a very small  
number of members of this forum, and guess what? from the 3-4  
individuals who do most of the development, maintanance, planning for  
future improvements. A simple application of a simple conservation law  
should suggest that every second they spend to answer trivial  
questions is a second less spent for more technical work that does  
require their expert contribution.

I think that all of us can give a bit more to this community. To start  
with:

1) For the youngest - Do not think that a free resource (the advice  
you can obtain on this forum) is unlimited. Use it sparingly and  
judiciously, after making YOURSELF a serious effort to answer your  
question. Remember that there is no better teacher than oneself. It  
may be painful to teach / learn from oneself, but a self-taught thing  
is learnt forever (not to mention your local mentors, senior  
colleagues, etc)

2) For the not-so-young - Many of the questions asked on this forum  
are general enough to be answered by any knowledgeable senior graduate  
student / young postdoc. Please, give back to this community by  
keeping the discussion alive without forcing the same 3-4 people to  
give all the advice that is requested here.

3) For the bravest. Join the developers' efforts by volunteering some  
of your time and help fix bugs / implement new features / start new  
projects based on QE.

For the time being, enjoy being with us as much as we enjoy being with  
you.
