Here's a simple tip on how to create link bundles on Bitly, the famous URL shortening service. Bundles make it easy to share collections of bitlinks (shortened URLs).
The first step is to connect to your Bitly account. If you don't have an account yet, you can sign up using your Twitter or Facebook account, or simply using a valid email address: https://bitly.com/a/sign_up
Once connected to your account, click on Bundles > Create Bundle:
Give a name to the new bundle and add a short description if needed.
Click on the padlock icon to make the bundle private (if needed) and click on Make Bundle.
You can now add the bitlinks of your choice to the new bundle
Click on Add a Bitlink to this bundle.
Bundles can be updated, deleted or shared with your friends at any moment!
