Add a column in threadlist

[Malk]

I have one specific forum where I want to add a column that displays the days the thread has been 'alive', days since posted.

Default is like this:
Thread / Thread Starter Rating Last Post Replies Views

I want it like this in 1 forum only:
Thread / Thread Starter Rating Born Last Post Replies Views

And under born is should say for instance: 2 days ago

Anyone know if such a mod exists or ideas as to where I should start off with this.

I well versed in PHP, but i've just recently started using vBulletin and as such still familiarizing myself with it.

Cheers!
