The User Interviews are an idea that have come and gone on the GCB over the years but have never really been something that has been seen to the end. Many users have done them, but few ever went beyond even 1 or 2 completed interviews. The recent re-incarnation of the interviews is done by Yoshidude81 and have been a success so far.
