C'mon guys, you need to know Paul. Read through his posts. Regardless of what you say he posted, once you read through his posts you will see he does give advice. Sometimes contradictory, often tongue in cheek, but always amusing.
Going from that point and moving to the general point of giving advice, I do not believe there is anyone here who selfishly only seeks answers to his own questions without contributing their own advice when they know the answers to some other questions. If you ask a question and get no answers, it may be that it's a slow day for posting, or that no one looking at the question knows the answer or is confident enough to answer the question. But, to know the answer and not give it? I don't think so.
There have been times when I posted what I thought was a well thought out answer or advice on a problem, and then there is no response from the original poster. Not even a thank you. Those times, I wonder why I even bothered to help, when the person asking the advice doesn't give a hoot or appreciate it. But, I still answer the next question I believe I know the answer to, and that next person may say thank you. And that one thank you will carry me through several other posters who don't say thank you.
