Branching of a discussion in forums?

[Alexandru Ermicioi via Digitalmars-d-learn]

Hi everyone,

So just wondering is it possible to branch off a thread into new 
one (viewable as separate item in forum group)?

Also, is it possible to branch into a different gruop all 
toghether?

I.e. from "blabla" thread in announce to "some other thing" 
thread in learn for example?

Thanks,
Alexandru
