Once a chat page (node) has been set-up and used by group of users, how could one periodically, or "on a button push", empty the current chat contents?

I imagine it involves querying the chat's field table for the nid of the page in question, and deleting all entries? But perhaps there is an easier way?


This would be of interest to me, too.

Version:7.x-2.0-alpha2» 7.x-2.x-dev

this sounds like a useful feature. patches welcome.
