Preventing replies to posts X days old?

[Ingenious]

Hi everyone, had a search for this but could not find anything. I might be searching for the wrong terms, I'm sure other forum owners have a problem with people replying to threads that are very old. The result is a very confusing mix of old and new posts.

Is there any way (or mod) where I can restrict certain usergroups (not admin usergroup) from replying to threads that have not had a post in X number of days?

For example, if a thread has no reply in 3 months or more, users cannot post a reply (thus enouraging them to have to start a new post)?

Or, I wondered if there was a simple hack that checks the date of the last post, and if > certain age, does not display the post reply button?

Still no luck on this one. Anyone? If there is no way of doing this (or no plugin that can do it) is there any variable I can check and write my own hack, eg. make the post reply button only visible if the last post < X days old?

I believe there is a mod that will automatically close threads afte x days. Do a search for "close*" in "all mods" "titles only" and you should find it.

Many thanks, that's given me somewhere to start

I use Automatically Close Old Threads After X Days . Nothing stinks quite like a community reopening old wounds.
