This is an example of a blogpost. On your homepage it said that most of the content of your labmark is on pages that are meant to contain information that doesn’t need to be updated regularly. If you however do want to regularly create blogposts you can!
You can create posts from your dashboard and they will automatically show up on the news page. Remember to assign a category and/or tag to the post, this creates extra dimensions for browsing the content of your labmark. Eg. you can have users visit a page listing all posts in the category education.
If you don’t want to blog simply delete the news page from your dashboard, it will automatically disappear from the menu in the left sidebar.
