Now admins have more power over their community members. You can "suspend" a user account on your community if the user account is spam, the person is posting inappropriate content, or simply the user's culture does not match with community's culture. 

How you can "suspend" an account? It is super simple. Go to the user's profile page and click on the (...) button on the top-right, then click on Edit. Change the status from "Active" to "suspended by moderators":

 

Once the user account it suspended, the user won't be able to log into the community anymore:

 

If you are a user and your account is suspended by mistake, you can contact your community admins via email. Where admins can set this email? 

You can add your community contact email from Admin Panel> Settings> General Settings> Insert your contact email under the "Email" section> Save changes.
