Beer club

I joined this online beer club, Beer52, the other week (I got a 3 months for the price of 2 offer). You get 10 beers a month from micro-breweries around the UK. The first box arrived today, there are some interesting ones to try in there. I'm not sure I'll stick with it when I have to pay full price (£24 for 8 beers a month), but you know, thought I'd try the whole beer connoisseur thing, although really you need someone else to join in so you can compare notes.
What is the first rule of beer club?
