change default thread display sort to alphabetic

[tribedude]

A forum in my board lists events. Currently it displays threads that have the most recent post in them at the top of the thread heirarchy. At the bottom of the forum there is a way to sort the threads by name (decending or accending) using a little drop down box, but you have to do this every time you want the listing sorted alpabetically..

Is there a way to set this so it lists the forum threads alphabetically by default?
