Prevent access to posts after a certain amount of time?

[tobias_t]

Hi, I run a forum about software, and because technology moves fast, old forum content mostly becomes outdated and therefore irrelevant or even potentially misleading after some time.

I would like to be able to define a "cutoff date" for the whole forum after which old topics become no longer accessible (or even visible) anymore. Of course they should still count for post count etc.

I am basically thinking about a global "show only posts of the last 2 years" setting or something along those lines. Is this possible?
