thread order

I would really prefer to read a thread in chronological order beginning with the original post. Right now I see the most recent post first and have to page through to get to the original post starting the thread. Is there a setting where I can set this up?

In the light blue bar above click on "Forum Actions"
and "General Settings"
Under 'Thread Display Options'
change to "Linear-Oldest First"
Then at the bottom "Save Changes"
