Hah, I have never seen people who, because of ignorance, deleted their post. Like, what's the difference? Maybe someone uses his advice, they just don't write about it, because they don't see any very important reason in this. If they want to ask or write something, they will write, just don’t need to be angry that message being ignored. IMHO, I repeat, but it's strange that this person deleted the message due to the fact that his appeal is simply ignored (personal opinion - nothing more)
