Question 128385
There are no guarantees on this site.
Sometimes problems arrive so fast they
drop out of sight on the list before
they get answered.
Sometimes the problems are poorly stated
so no one can tell exactly what the 
question is.
Sometimes the link drops an important part
of the posted problem so it makes no 
sense when read by a tutor.
There are many reasons why a given problem
might not be answered.  
So what can you do?
1. Make sure your questions is complete in
its posted form
2. Add a plea to your posting if you truly
need an answer by a certain time.
3. Make your best effort to solve the problem
and point out in your post where you get stuck.
Cheers,
4. Don't shout (posting the same problem two
or more times in successive minutes) but do 
repeat the question after a suitable time has
elapsed.
Cheers,
