How to exclude threads by admins from forum listing?

[TWood]

I want to modify the 'forumdisplay.php/2-Main-Forum' file so that all posts by my two admin user names will not show up in the list of threads. I'm auto-generating a lot of threads from the admin accounts, and I want just threads from other users to show up in that list. How would I go about doing this?

Thanks!
