Hi LeroanZ,
To create a blog page on K2 :
- Create a K2 user group with author permissions (add/edit/publish items)
- Create a K2 user and assign him the K2 user group previously created
- Create a Joomla! menu item link 'K2 / Item listings / User Page (blog)', select your K2 user.
When this user will publish an item on frontend, it'll be automatically added to the blog page.
You can set the 'publish items' permission to no and moderate the item publication in backend, if you want.
