Warning users that a thread is more than "x" months old prior to posting

[Marcus]

Is it possible to implement a feature prior to posting in a thread that is (let's say) 6+ months old to warn the particular user that it is a dated discussion?

Thread resurrections are common in the basses forum (typically) by newer users that do not realize the thread was incredibly old.

Only point is that this may lead them to start a new topic about something that they perhaps should have searched for and read through before making a new topic.

I see nothing wrong with posting to an old thread...in fact I have seen many old threads resurected and then receive another twenty or thirty new posts

Bumping an old thread is infinitely better than starting a new one as far as I'm concerned.

When searching, I'd rather read 10 threads on Benaventes with 100 replies each than 100 threads with 10 replies.

I search daily.

Math is fun.
