i think i can do this for you.

at the very top of this page, on the right side, in the black bar, it says settings. click on that.
on the new page, on the left side column, under the heading accounts, click on general settings.
on the new page, in the center, scroll down to where it says thread something or other and choose the default you want.
you want Linear Oldest First.
