The settings section is where you can configure and customize everything about how your blog functions and works.
General Settings allows you to change the following:
- Blog Title
- Blog Picture (also known as a Blavatar).
- Tagline – A short description or catchy phrase to describe what your blog is about.
- Email Address
- Date Format
- Time Format
- Week Starts On
This section allows you to delete your blog. To delete a blog, you can go to the Settings > Delete Blog page. An email confirmation step is required. If you delete a blog you will not be able to get it back and no one else will be able to use that blog name. You must be sure you never want to use the blog again if you delete it.
The OpenID Settings page is a place to configure the trusted sites that can use your WordPress.com blog as an OpenID login. OpenID is an open standard that lets you sign in to other sites on the Web using your WordPress.com account. This means less usernames and passwords to remember and less time spent signing up for new sites. For more information follow this link: http://en.support.wordpress.com/settings/openid/
The Domains Settings is where you can make changes to a mapped domain.
This page is identical to Upgrades->Domains. Please visit the previous link for more information.
