This fortress went surprisingly well, but I don't think I could get any immigrants, is it possible to get them on a island even is one edge of the map is land covered? Secondly I went looking for my volcano only to discovered it was under an obsidian cap under water, is that a bug? It showed up as a volcano on the big map.
I don't play on islands, usually, but I've read that the dwarven caravan and migrants can always find you. How much time has gone by in the fortress? 'z' to get the year and season. I wouldn't worry about this until summer of your second year.
As for the volcano...hey, it just says there's a magma pipe, not necessarily that it'll be easy to get to. You can still dig to it.
My second try was on a road square, which happen to have a brook, and a magma vent. Only when I embarked I discovered that the 'rock' was just a flat path with a bridge, that the brook was frozen all but 3 months of the year, and between the chasms, and the magma vent I had a massive list of nasty stuff in the area.
Access to the depot can be blocked by boulders, trees, etc. Ivefan and Footkerchief covered this well enough.
You don't say why you want to melt the brook, but if you want to keep water from freezing, get it somewhere subterranean. Temperature doesn't vary underground.
The job manager is good when you want a lot of something, and don't care the particulars. But it's bad if you tend to want one thing, *right now*, or want specifics (making sure it's made by a really skilled worker, or with a specific item type).
Chasms tend to have nasty stuff. That's what makes them fun.
On the bright side the soft soil makes for a quickly dug fortress on the down side my soil made ramps seem to keep clasping can anyone tell me why?
Ramps do not provide support. The two usual reasons for ramps causing collapsing is you dug ramps all around a tree, or you dug ramps that cut off an overhang. Both are annoying. Except for getting a path to your trade depot, if needed, I would recommend using stairs instead of ramps, as they provide support, and so do not cause this problem.
The aquifer is not going to help you make a waterfall. =P
I would imagine your trade route is blocked by trees.
