LinkedIn Groups are a great way to get more value out of your professional network. You can discuss topics with like-minded people, and get to know them on a more personal level - kind of the goal of networking in the first place.
I participate in a number of Groups on LinkedIn, including several for job seekers. One KC-local job club, New Landings, frequently posts job leads as "Job Discussions" on their LinkedIn board. Job "Discussions" are slightly different from regular job posts, and some newer members have trouble differentiating/finding the Discussions. So I put together this screenshot tutorial on How to Find Group Job Discussions on LinkedIn, to help them find their way to a "New Landing".
