autodelete old topics

[MegaS]

I need to delete old topics from a board. How can I do it? For example, I think to create a crontab job. Which sql statement shoulld I run to delete topics older than 30 days? Or may be use RemoveOldTopics2() function?

You could just goto forum maintenance in admin, and do it from there.

I know.
I want to do it automatically. So I need to write a script.
