I know this, and it's obvious to anyone who's ever read my posts.

Yet, from what I've read, I'm supposed to post what I think of other people's posted hands? Is this correct?

I mean, I want to do it, but at the same time I feel like an idiot saying what I think to a guy who's got 3500 posts and who plays $10/$20.

Should I only post on lower limit hands, or should I give my opinion on anything, or should I shut up and read and not post at all until I have a better idea of what's going on?

What's the guidelines here?
