How can I link people's names in a post?

You can tag your friends and other things you’re connected to in your Facebook status and other posts. This feature works with the share menu at the top of your home page, your profile and your friends' profiles.

1. When you want to create a tag, type the "@" symbol in the text field. Or, type the first letter of the name you want to tag in caps.
2. Directly after the "@" symbol or capital letter, continue typing the name you would like to tag. A drop-down menu will appear with all matching entries. You can tag friends, Pages, groups, events and applications.
3. Select the name you would like to tag. It will appear as a link in your post. You can tag multiple different names in the same post.

People who can see your post will be able to click through to view the profile, Page, group or event you tag, but only if the existing privacy settings permit this.

Tagging allows you to more actively mention your friends and other things you are connected to on Facebook. It also lets you direct a post at specific people while still keeping the conversation open. Friends you tag will receive a notification and Wall story that you have tagged them, and also when someone else comments on a post they are tagged in.
