An approach I took on the matter of a forum gaining a large amount of post was to first install the mod [
https://vborg.vbsupport.ru/showthread.php?t=113324]Auto Delete/Move Thread After X days [/url] and explore this mods capibilities.
A close inspection of the mod as orginally wrote allowed post(s) to be moved from forum(s) to a single destination forum.
What I wanted was to have the main forums on my site with the latest post and sub forums nested within each main forum holding posts from 120 days past. Using the
Auto Delete/Move Thread After X days as a model I then changed the code to
https://vborg.vbsupport.ru/showthrea...=113324&page=3 post #35. Which then allowed me to specify a souce forum to destination forum moves (main forum and 'archive' forum) as parameters. Now my main forums contian the latest topics of discussion (small db return result sets) and those main forums contain 'archived data' (large db result sets).
The mod runs as a cron job.
