Julie.....To invite someone hit     new post
( instead of posting ) hit.... settings
hit..... permissions
type in email address for new 'poster'
hit..... invite
at that point I am not sure,  but I think they get an email  invitation to join .....    then we have to revisit that screen and hit  "make" ?  administrator...something like that.......  I will watch for her to respond
I usually check the blog every day for new posts

I invited Walsh, she should have invitation.(((((((((hug))))))))
