Permission to view certain forum after X posts

[ski diva]

I want to automatically allow registered users who post a certain number of times to view a certain forum, and automataically deny permission to registered users who haven't met that criteria. How can this can be done?

Either through a promotion and permissions/access masks or through a hack such as this one https://vborg.vbsupport.ru/showthread.php?t=123002
