Day 2 - customizing my Blog

Day 2 - customizing my Blog

Todays job was to play around with the theme and ;layout to personalize my Blog

I went for a pink theme.

I then managed to tweak the layout, but my problem is that I don't actually know how to get to the main page to see my blog! I can only see it in its editing format.
I feel like this is probably a really easy task, but I feel rather inept.

Current questions which I hope I find the answers too.

Can anyone see my blog??
How do I see my bog in its pretty pink format??
Where does it go when I publish it?
What's the difference between publishing at saving??

So many questions
