Returning to 1st page of Posts after Posting Reply... HELP??

[theothersully]

My installation of vBulletin (3.7 patch level 1) is returning to the first post in a very long thread instead of the last post when people are replying.

So, they hit reply at the bottom of the screen, enter their post, submit it, and vBulletin puts them up to the very first post in the thread. Quite annoying.

Where is the option to change this so that it goes back to the last post in the thread, like this website does?

Thanks.
