With Wix Blog, you’re not only sharing your voice with the world, you can also grow an active online community. To let readers sign up and become members of your site, add a Members Area from Add Apps in the Editor sidebar.
Members can follow each other, write and reply to comments and get notifications. Each member gets their own personal profile page that they can customize.
You can make any member of your blog a writer so they can write posts for your blog. Adding multiple writers is a great way to grow your content.
