LinkedIn , the world’s largest and most powerful online professional networking website, has created one unified networking group under the name “Kappa Sigma.”

If you already have a LinkedIn account, you can click the above link to join the group. If you do not have a LinkedIn profile set up yet, you can go to www.linkedin.com to get started. The basic version of the service is free to users and only takes a few minutes to get up and running.

The concept of LinkedIn is to serve as an online professional rolodex and business tool, allowing you to search for jobs, post your resume, search for services offered by Brothers, etc. The site is built around users establishing trusted “connections” and professional relationships, among people they know and with whom they have worked.

More than 20 million professionals are on LinkedIn, including executives from all of the Fortune 500 companies, as well as a wide range of household names in technology, financial services, media, consumer packaged goods, entertainment, and numerous other industries.
