Hello Abe.
i was thinking about a force users to read a pm
a pm sent by a Mod or Admin or perhaps configurable for other usergroups too via Admin Panel or something.
i have set up in my forum a flashing PM icon to get a member's attention but maybe that could be a nice idea too.
to be honest, i haven't checked to see if such a hack exists but i'm just tossing around some thoughts here.
tnx for reading.
