BUKF has an Archive where threads go after they pass on from this world. The Rules for the Debating section are simple enough. A thread will disappear from here and go into the Archive when:

1) no reply has been made for six months

2) a thread receives no more than 2 replies after one month

3) a thread has been closed


So if you're looking for something that, say, Zoro said last year about global warming, try the Archives.

Threads will be retrieved if the topics become an issue again.
