Its pretty easy actually.
Just download NewsSearcher from: http://z14.invisionfree.com/NewsSear...?showtopic=177
Direct download link:http://rapidshare.com/files/11810029...stall.rar.html
It integrates into newsleecher (works with 3.8 final) without being noticed.
Altough there are some minor side effects, it convinced me and ive started using Newsleecher since I noticed this great tool.
(ive reposted it in a.b.comp along with nl3.8: http://www.newzleech.com/?p=2555765)
