Yeah, I've been meaning to do that for a while but nobody asked so I put it to the bottom of list.

I suppose I'd better move it up the list now. :)

This feature has now been added.

If you want to hide usenet posts from a search, just check the box on the search page.

If you want to search <i>only</i> usenet posts, then you can simply select the appropriate forum from the drop down. All child forums are included in the search, so you can simply select 'Usenet Groups' from the drop down.

If you select a specific forum or category to search, the 'Hide usenet' filter is overridden.
