Edit. It doesn't always work though but try it and report here what happens.
There is a description somewhere here in LQ?
As I remember one should read the email from them very
carefully and do as they say. I am very bad at such so
I failed to get exactly what was expected of me so I gave
it all up.
I didn't trust they wanted my very naive questions anyway.
But don't give up search for the descriptions on how to
do it. You have to write to a special address they gave
in that first letter one receive.
The reason they give is to sift out those who want to spam
them. Bots and such but they have done it very hard for us.
I'm sure they sat it is super easy. It is always easy
for somebody who gets how to do something.
