You can review your contacts and connections from the "Contacts" tab across the top navigation.

You can then see all your contacts and begin organizing them into groups or exporting your connections as a CSV file to then add them to your mailing list (note: we'll get to how to do this soon, but be sure to only add them to your mailing list if you have their permission to do so).

LinkedIn also allows you to import your contacts in bulk if you don't have the time to search for them one by one. You can either search your email address for contacts or, if you have a CSV file of all contacts you'd like to connect with, you can go ahead and upload that in this menu:

You can even browse old organizations you would have worked at, a school or college you attended and add those connections to your network.

To connect with past colleagues click here.
To connect with alumni for college click here.
Or if you just want to browse people you may know, click here.

As with any social network, there's always a way to remove a connection if there is need to. You can do that from the Contacts page by selecting a contact from the menu and clicking "Remove Connection" button, and then clicking delete to confirm.
