Blog Settings

I am setting up the blog so that if you like, you can add pictures or blog entries when the spirit moves you.  To do that I need your email address so that I can send an invitation.  I have not done this before so I am rusty on the particulars, but it looks like I add you and you can access the inner workings of this blog.  I also have it set so that anyone can comment on any of the posts even if they are not a "member" of the blog.  If you see anything wrong with my thoughts or methods, please let me know.  Thanks!!!!!!
