Bridge tips?

[Tilty McTilterson]

Can anybody give me advice on how to hold my own in an informal bridge game?

I know the basic rules, and that's about it. I realize that it takes years to be a master at bridge. Luckly, I don't need to be very good. I just don't want to embarass myself.

What's the most basic advice you would give to a beginner (bidding, card play, how do you keep from being bored to death when you're the dummy, etc.)?
