Well, just spent a couple hours getting everything working. I'm completely new to this, so I wasted a loooooot of shots. But I'm starting to get the hang of everything. One initial problem was simply installing the lever the wrong way, it kept getting in the way of the portafilter

. Two quick questions:
Tamping - is it recommended? I seem to see some people who do, some who don't. If you tamp, you have to run a coarser grind, correct?
I ended up getting two drinkable shots, which I'm happy with (one had that bubble type look as it came out of the portafilter, looked yummy). I'm used to a caffeine dose each day, so as morning progressed - I was racing against the clock to get something I could drink!!
