This is your professional blog. This blog is for you to talk about projects you're working on, talk about what's happening in your industry and anything else that's related to your profession.
This is the focal point of your network. Your members can comment on the posts and interact and discuss with other members. You'll be able to kick start discussions and members can chat and comment on what you're up to.
You can 'tag' each post with relevant search terms so they can be archived and readers can find them by theme. You're now able to add a feedback rating to each blog post so you get more of an idea about what your members are looking for.
You can add links and images as you would with a rich text module. As well as highlighting important passages. It's also a good idea to add a relevant photo to the post to make is more engaging.
Don't forget, you can amend the title of your blog, and delete this post once you get started.
