procedure for joining an existing blog as an author/blogger

Dear Sir,
My blog titled : Indialibrarian Internation ( blog address :
http://indialibrarian-intl.blogspot.com) has now more than 45 guest
bloggers/authors. When I send my invitation to some of my friends they
are unable to accept the invitation. I mean they are unable to
understand. Do you have some literature to educate budding bloggers in
this regard, which I can post to them for guidelines?
With best wishes
