Send email to member that posted only in a specific forum

[abrecher]

I really need the ability to communicate with members that posted in a specific forum. Is anybody aware of a mod that can accomplish this ?

Sorry, no answer, but I have a similar requirement - I'm going to start charging for a particular sub forum, and I want to give free memberships to everyone who has already posted in there - is there any way of finding this out without manually sifting through? Some kind of database select/view?
