group leader mass PW

[jedrus]

Hi,
can you tell me if there is any possibility to that the group leaders can send mass PM oraz mass emails to members of their group? I need this functionality in my forum...

Maybe someone could tell me if I can do it with myself, i.e. based on
Yet Another Mass Private Message System.

I'll be thankful for every help - my group leaders must inform their group members about week's meeting place and date and there isn't any other simlpe way to do this...
