Perhaps some of the members are hesitant to post more because they don't think they are as knowledgeable as some, or don't feel they have anything new to offer. IMO that the opposite is true. It's kind of like my job: I've been doing same job for almost 18 years now, and I think I'm pretty good at it. However, even though most of the younger employees look up to me, and come to me for advise, not a day goes by that I don't learn something new from them. So, yea, I welcome input from everyone. No one knows it all, or has done it all. Everyone has something they can bring to the table.
