Is this place private?

I've introduced myself here before, so I'm not new. In fact, I check in here everyday. I posted a thread titled "What combo to buy?", and there hasn't been a single response to it. I thought you guys were here to share and help each other.

Is the sharing and helping only amoung a few "regulars", and newcomers are not welcome? I thought I followed proper etiquette the first time I visited by introducing myself. If that wasn't it, could you please give me the "secret password" or "handshake", so I could join in too? Thanks!
