I found this ladies web site, she has done Usborne for a while now. If you e mail her, she can send you an info pack then offer you advice and support.
It seems better than just joining straight through Usborne as you have some supoort.
I have been asking her loads of questions lately and she has been really helpful

Her name is Amanda. Should e mail her and ask her about it
