I have thought the same thing!
However unless your prepared to put in the time and respond to other peoples posts then you cant really complain when they dont reply to yours!
Forums are a 2 way street. I have run several forums and some go this way due to participant reluctance to answer other peoples posts, and some end up the other way with every thread going off script!
when you dig into it, you might find that people are reluctant to give experiences for several reasons, 1. They are busy people that just dont have time to browse. 2. Their own experience isnt vast enough to be able to answer your question, 3. theres been a history of abusive messages when something isnt 100% and they dont want to face abusive messages. 4. not enough regular visitors and people only come online to post when they have a problem.
