Even tho it is a bit off topic here and there, I have still gotten quite a bit of useful info from this thread

I tried a new barracks now, just one big room in my new fort. So far I am having problem getting my only squad actually train there. I set them for 4/8 to train at a minimum, each month, but it is usually only 2-3 of the squad there only. But when I command the squad to do something, 7 usually show up. (Despite being failry skilled, they came with skills in the range of 2-4, so they are not total noobs, and manged to kill a hydra without injury, but a goblin hammerman mange to hurt their bons pretty bad, despite all steel armor).
I have not used danger rooms either. They kind seem a bit too easy and broken-ish. Now that I have a decent grasp on military and traps, I find regualr training seem enough for goblins, and the odd beast. I have yet to face a real super beast tho...

Yeah, rocks seem to be in abundance. Sometime I try to make marble crafts (assuming I have plenty of it) so that I get that nice 2x modifier on worth.
