Right then, First things first...
I am thinking that now that the Founders are at the Fort, 800☼ is too much for migrants, Perhaps lowing it to 600☼ due to the fact that they do not have a Wagon to take their equipment and must lug it in a backpack or in their pockets. Perhaps changing the List to reduce different items and such making it a little harder/easier for them to carry only really what they need to do THEIR jobs when they arrive and not bring Excuss items that fill what the founders forgot to bring. Perhaps include a Wagon for sale so that they could group up with extra dwarves if the Migrant Roll gives a large amount of people but forcing them to wait an extra month to arrive (same oragen style entrance perhaps)... I don't know, mulling it over, so to those that have had posted Migrant Profiles, please tell me if you feel that I am being to harsh on you or that it seems more likely. I do not want the Migrants asking OCC to those at the Fortress, "Hey what do you need???"...

If we do build an open-faced tunnel under the waterfall, will we ever have to worry about it sucking people off, or the slimy stone making people slip? It doesn't matter very much now, but eventually this will be a grand place and I'd rather our main entrance doesn't resemble a slime-filled gutter. Of course, we can eventually redirect the river, add flow controls, retractable shutters and all that. The river freezing in winter should allow us to work fairly easily, though all the wet surfaces turning into ice slicks isn't very attractive...
Question: Will we eventually be able to make connections to the icebergs in winter (rope bridges?) and hunt penguins and seals on them?
Heh its a Major river that is a Waterfall, it don't freeze, the force of the water falling over the cliff and its speed does not allow the water itself to freeze over, if I am right in say, it happens like this IRL too... (Aussie so don't even know what Snow actually looks like except through TV).
Connecting to the icebergs is a possibility, but they will not be staying still due to the fact that its not an Icecap here, they will be moving alot so permanent connections is kinda impossible in the end, perhaps if a boat was made, but Dwarves don't know much about boating really...
and finally...
Also, when do we pick a leader?
Your too worried about the Goblins to bother about politics of an outpost that doesn't really exist atm. Perhaps after you feel more safe, at the moment, its more a big discussion on how you are all going to live and what to do next....
