Working sharing the Blog!

Well as I'm preparing to leave for Asia on Thursday and I am trying to understand my blog and get it going.  Right now I would like to limit it to people I know so I am working on how to do that and get my blog address added to my email signature so that people I email can click on the link and go straight to my blog.  Not happening yet but hopefully soon!  Am posting this as I believe changes I make do not become active until I blog....here goes!
