I'm on the home server at the moment. I bumbled around making a fool of myself until I ran into a nice anarchic community due south from Newtown. We're at least three DF:ers there, two of us with houses so far. I've got a workshop set up with a forge for smithing and an oven for baking.
To find your way there, head south along the main north-south road in Newtown. After a long, steep incline (nice view if you look back) there is a road branching off to the east between a chimney and a small hut. Follow it west and observe the mountain to your north and the valley on your south (don't fall - it hurts) and aim for the guard tower. On the plateau is my workshop. Please don't crowd it, I am planning some expansions.
Oh, and do speak to the others before you settle. There's no de juro community leader around, but past my place there's a workshop of a couple of people who seem to be the ones who have their act together the most and that I look to as authorities. I just can't remember their names at the moment.
Apart from us DF:ers, and those guys (who I'm getting hooked on DF as we speak) there seems to be mostly a bunch of guys in their early teens, some of them from Sweden.
There's also a mine which appears to be communal, and there are forests nearby. Be nice and don't abuse the resources.
I also heard of a DF community west of Newtown... Can anyone confirm this? If it exists we need to chart out the route between us. And as responsible dorfs we need to tunnel between them, too.
As for tunneling, you can't rewall, or build walls at all underground, so there'll be no doors underground, unfortunately. But since when did we dorfs need that sort of luxury? Pah! When I started out, we didn't have pickaxes. We had to beat the rock with our fists until it cracked. The feeble and unfit were put to work smoothing walls with their fingertips. We didn't have anvils either, so we used our heads. We drew lots of who'd be the anvil each day (and Olīn Crackedskull had a lot of bad luck). Since we didn't have forges, or fire, we had to rub the ore with our hands until the friction made it warm enough to work.
Ahh, those were the days...
