How do I warn lurkers?
 

How do I suspend "Lurkers" (active members who never post) accounts, and automatically send them an email notifying them that the have been suspended for not making x number of posts, in X number of days.?

Then , of course, requiring them to request that there accounts be reinstated?

Thanks for any help, in advance.:)

Maybe do something creative with the infractions system.

Wow. A board that requires participation?

X posts in X days? Sounds fascist.
Do you really want people posting nonsense just to make their quota?
