The links in the old software were identified completely different than in the new software. I really don't know why you would want to link to something in the old forum, since it will be in this forum.
Anyway, the old software used an ID number for the thread, which according to the link that is posted, it is the ID number for Warez's Spyware Removal and did go to that thread. The new software uses another type identifier. For example, instead of the link above to Warez's thread, it is now http://www.techist.com/forums/f51/wa...-guide-114061/
If you're trying to link to a thread for reference, you'll need to use the thread in the new forum software.
Was that understandable?
