Pruning - Quick help.
 

Greetings..

I'm trying to prune my forum so it's ready for v4.0 but the settings are just a tad tricky. I want to remove posts that are older than 6 months but the boxes within the pruning selection is what's puzzling me.

Can someone just run down the settings for each box (top to bottom) so I can get this done please?

Many thanks.
