if you search through the archives you can find old threads. if you respond to an old thread then you bump it up so that it is the thread with the most recent post on the forum.

e.g., i just brought my 'nailbiting' thread that was a couple pages into the archives up to being one of the newest threads on the board by posting a new response to it. (though who knows whether it will still be on the page by the time you wake up)

;-)

so zen bumped the whole thread out of the archives and onto the current pages. each post is dated but i don't often check the date. not sure how much people bump things out of the archives.
