How to Join LinkedIn without an Invitation
Your account is created, and you are now free to start building your network and updating your profile!
You are taken to your home page where LinkedIn asks for information to help build your profile.
In the meantime, if you want to take a break to check your e-mail, you'll find a nice Welcome to LinkedIn! message there from LinkedIn Updates, assuring you that you're now a registered LinkedIn user. The e-mail encourages you to connect with people you may know and offers to take you back to the website to search for more people to add to your network.
