Your personal URL is generally your username or user id number, though many of the social networking sites below let you choose the URL you want to use. If you don't already know the URL for your public page on any of the networks you belong to, please check their help topics.
Notes:
1. For Facebook, just log on, go to your profile page and copy the complete URL from your browser's Address field.
2. For LinkedIn, you'll need to use a custom URL To customize your LinkedIn URL, go to http://www.linkedin.com/myprofile and click the Edit link to the right of your Public Profile.
3. Flickr does not assign public URL's automatically. To get your Flickr address (aka "alias"), go to http://www.flickr.com/profile_url.gne
