I know you can change the order of messages a little through the "Installed mods" in the admin section.
When viewing a thread, if the option "View Newest Messages First" is checked, it will show the newest message first in a thread.
Doesn't make a lot of sense to me to have this checked. Say you have a 3 page thread and your click the thread's title. You are brought to the newest message first and then have to click on page 3 to see the start of a thread.

If there is a mod out there, I don't recall seeing one... but dig through the mods section just in case. You will love SE's stability, though.

The last thing I remember doing with Gold was moving a thread and half of my messages vanished. I took the board down right then and there, went to work and started converting over to SE!
