Help with sorting posts

[Salsero]

Hi, I've recently done the upgrade from YabbSE 1.5.4 to SMF 1.0.2 and I realized that all the postings are in reverse order i.e. the original post for that topic is at the bottom and the last reply is at the top.  How can switch that so it's the other way around.  I would like the first posting to be on top and the replies underneath in order they were posted.

Thank you.

Profile -> Look and Layout Preferences
Uncheck the box next to "Show newest posts at the top".

To do this for all users:
Admin -> Current Theme's Settings -> Reset default member specific options, check the first box, leave the second one un-checked.
