BLOG SETTINGS

There are some tabs you have to be familiar with. They are 'posting', 'comments', 'settings', 'design', 'monetise' and 'stats'.

To begin with, have a look at 'settings'. There you can, for example, delete or export your blog, choose the time zone, the language, the date header format, decide who you want to see your blog, and so on.
If you click on 'stats', you will be able to see how many people have visited your blog, where from, etc.
Some other tabs I would like to comment on are 'design' and 'posting'.
Posting allows you to start a new post, edit all your posts (edit, view and delete) and edit pages. In order to publish a new post you can go to this tab or click on 'new post' on the top right part of your blog.
Design is  where you can add and arrage page elements called gadgets (labels, slideshow, text, search box, link lists, text, etc) and choose the template designer.
