Discussions on LinkedIn are a great way to communicate with others in your niche and build connections with like-minded individuals. To start a discussion in your group, hit the ‘Discussions’ link at the top of the group page, and add a title and description for your discussion. You can add an article, ask a question, or post relevant content with a link to your company page, website, or blog. You should also check to see if your group has a special section for adding promotions and jobs.
You can participate in discussions by liking and commenting on the discussion, and following a particular discussion to receive updates when someone comments on the post.
