Rudeness or Ignorance ?

Hello,
I am new to Astromart. Over the past 2 weeks I have responded to 6 ads in the classified section. 3 were questions about the item and 3 were requests to buy the item at the price and terms listed by the seller. I have never received any reply from anyone.
My question is ... Are they being rude, or am I being Ignorant and missing some protocol required by this board ?

Thanks ... Fred Dase

I was expecting the replys to be in my message inbox here at astromart, not in the email account I used to sign up.

My Thanks and Apologies to all those who offered advice !!
