is there a mod can DETECT and Automatically DELETE DUPLICATE threads??

[neopet001]

I remembered there 's a hack that can find similar thread title when making NEW post, just that!

Now I've some mess in controlling moderators' threads, so are there a modification that can automatically detect and/or show me to delete the duplicate threads?

Thanks for any help.

I really need it. :(
The duplicate threads are making me crazy :((

I solved it by editting the misc.php file , use in Update Counter section.
Thanks
