The dashboard gives you a quick overall summary of your account.  Each of the overview sections shown on the dashboard are fully covered in their relevant sections within this guide.

For your Wishlist, Feedback and Store – clicking on the >> next to each of the titles will jump you to their relevant My Account areas.

Below these items you can view lists of Unread Messages, Current Bids, Purchases and My Sales.  Each of the lists will give limited options compared to their relevant section within My Account.  For example, under My Sales you can see a list of sales but the only actions are to print the invoice, send a message to the buyer and leave feedback.  You cannot update the sale without going to the Sales area.  

Each of the lists has a button at the top right, enabling you to jump straight to their relevant My Account sections.
