Blogroll to Links
The previous option of Blogroll has been moved to Manage -> Links. You can add links here or from Write -> Link.
You can add categories for your links by going to Manage -> Link Categories.
Now that 2.7 has launched, we are working to finalize a new Support site. If you can't find what you are looking for in the new Support site, come back to faq.wordpress.com.
