To start with, I'm just digging a basic 1x2 tunnel, so we can expand and decorate later.  I've got my station more or less done, except for decoration and such, and I have the starting tunnel to Overwatch mostly done.  Once everyone is connected by basic tunnels, we'll start expanding.  A 3x3 tunnel sounds best, possibly with the walls done in stone brick, or glass where there's a particularly impressive lava cave.  I've looted a few mineshafts for tracks, and I have enough iron for a lot more, but I think a single track between towns would be best until everyone is connected.  Once we've got single lines done, then we can double-up to make to-and-from rails.

EDIT:  The initial tunnel to Overwatch is done.  The tunnel ends just outside their town, with a small cobblestone marker outside the west gate to show the way down.  Cities to the south of Bloodtopia should be easy to connect to now, as the tunnel I made went south for a long way before heading east.  We can make a small station to change tracks where the tunnel turns.  Anyone who wants to explore the tunnels, my station is not behind any doors, so head on over.  It's outside my walls too, so anyone can go in.   Eventually, I'm going to set it up so that only allies can go in, but that's too much work for now.

Additional Edit:  Anyone looking to help on the subway, bring weapons.  For_Pony decided to camp where it meets a cave and kill people.

I want to make a subway that connects everyone who lives near me and isn't a jerk.  I'm thinking digging at or near bedrock will easily pass beneath any ravines or oceans in the way, and has the advantage of being fairly secure against griefers, since they'd have to find it first.  To be safe, the subway tunnel should be lined with something that's obviously not natural, so anyone who mines into it will know it's not just an abandoned mineshaft.

Thanks

I was reworking my blaze spawner, broke the spawner, and it did not drop.  No lava, hoppers, clipping through blocks, nothing.  Featureless stone room, used a pick, no drop.  Any chance of a rollback, or do I just need to buy another from someone who has a spare?

It's quickly becoming Thief.  The stealth mechanics are a little less clear-cut than the original series, but I'm very impressed by what I've played so far.  Stealth mechanics in games tend to be very simplistic, and the Thief series is arguably the greatest stealth series ever made, and the first chapter of the new one feels like the old ones, right down to Garrett's voice and the subtle sense of self-satisfaction as he burgles his way through the city. 

I'm not the only one who can't get onto the server.  It's been a while to, which makes me think it's not just a restart.

GOD SO GUUUUD

Meh, Metallica is good, but they kinda got old and cranky and boringly well-known.  Somewhere along the way, they became the metal version of dad rock.  Try Ensiferum.  Technically, they're Melodic Power Death Viking Metal, but you can shorten that to "awesome."  If a metal band doesn't look capable of burning at least a small town to the ground, they're not awesome enough.
