At the end of the day, in forums and in life, all you can do is offer your opinion. If the person doesn't take your advice, don't take it personally, no matter if you're 1,000% right about what you said. I used to think like you and it's a good way to feel stupid. Don't let it get to you ;)
Thank you, I just got carried away, I invest time in answering a question and then it becomes like a personal problem although in reality it's someone else's problem.
You're right.
