Prevent users from bumping old threads - VB3

[djnoz]

I'd like to see a hack that allows you to place an expiry date on threads.

For example:

Expiry date for a forum is set to one month. The last post in a thread created within this forum was made over 1 month ago.
A user tries to post in this thread and meets an error message telling him that the thread has expired.

This should ideally be implemeted so that it can be switched on or off for different forums. If I have an articles forum, I want to make it so that users can make a comment on that article even if it's past the expiry date.

If nobody makes it I *may* take the challenge and implement this myself.
I think a LOT of people will find this useful.

Forgive me if there's something already like this for VB3.
