You can use the team member section to create all sorts of posts, ones that congratulate someone in your team on a work or personal achievement, celebrating birthdays or work anniversaries, introducing your new team member to your audience. They're a big tick in the 'getting to know you' box and people tend to love these types of posts.
You can create these posts as and when you need them, we really like to create a few so they're ready to go when they pop up in our 'to be approved' section.
You can add team member posts to your team member library at any time, you'll find this under the content lab. Just click 'add team member posts'.
