Auto-subscribe usergroup members to forum

[Burley]

Like the title says, I'm looking for a mod or code aaso that upon registration members are subscribed to a specific forum. So that if a new thread is posted, they will get an email.

I've searched and tested several mods, but none seem to do exactly what I'm looking for. I know I'm not the only one who wants this, so does anybody know how to do this or which mod to use.

I'm in the same boat.
I need one for usergroups.

Thank you in advance.
