Require a Payment to Post in a certain section - possible?

[Noctavia]

I want to set up a section of the forum, that is open to posting, but before you can make a post, you need to make a payment.

So basically:

* person registers
* goes to forum section A
* hits new thread
* gets message saying 'you must donate $2 to post in this section'
* person pays $2
* person can then post their thread

Is that possible?
