If you want more respect given to your questions, try the following:
use correct grammar and punctuation, do some pre-research
yourself first, limit your questions at first to one or two.

An example here would be to mention product numbers 
for the things you're trying to get information on.

Show some respect To the list, and you'll get more From it.
