When you log in to WordPress, you will notice a blue bar at the top of the page, this is your navigation bar. Here’s what’s on it:

My Account: Global Dashboard-what’s going on in your blog, what’s hot in other blogs
Tag Surfer: Subscribe to tags and see posts with those tags.
My Comments: Comments you’ve made on other WordPress.com blogs, plus the comment right before yours and the one right after.
Edit profile, Contact support, the WP.com home page, and the Log Out link

My Dashboard: Where you go to write a new post, or manage previous ones, plus a whole lot more. The only difference I can see between My Dashboard and the New Post link is that the New Post link takes you directly to the Write Post page. I always just go to My Dashboard.

Press This: One of the most confusing things I have ever seen on any blog publishing platform. On the very right side of the blue navigation bar is a white arrow pointing to the right. That is a link that takes you to another random WordPress blog. If you find a blog that has something you want to write about, click Press This, and you will be taken back to your Write Post page, with that URL already filled in. If you just click the Press This button while you are on your own page, nothing happens.

Blog Info: Again, for surfing other blogs. There is a subscribe to blog link, and buttons to report other blogs as spam or as “mature”.

You can find a lot of great information just surfing around on your navigation bar!
