Auto-prune/delete

[JoeWho]

How can I auto-prune enabled/disenabled or set specific forums to prune/delete after a certain amount of days?
I did a search on these forums and found (http://www.vbulletin.com/forum/showthread.php?t=141883&highlight=Auto+Delete+30+days)

But that did now work for vB3.5, I received an error.

Can anyone help?

Thanks,
