Only those who you approve become site members.To require approval for site members:
Go to Signup, Login, and Security in your site's dashboard. Under Who can be a site member? select whether you want everyone to be able to sign up or only people you manually approve.
Click Save.Blocking or deleting site membersYou can block or delete any member who does not follow your forum rules. Blocked members: Cannot like or comment on a post or follow a writer. Blocked members do, however, appear on the members page. Deleted members: Cannot like or comment on a post or follow a writer. All the site member's posts, comments, and likes are removed from your forum. The member no longer appears on the member's page. To block or delete site members:

We recommend limiting access for approximately one week.  To limit who can write posts in a category:
Click the Wix Forum app in the Editor. Click Settings. Click Manage Categories. Hover over the category you want to edit and click Edit. Scroll down to the Post permission section and select Admin and moderators only. Click Save. Repeat steps 4 - 6 for all other categories. Require admin approval before posts are publishedIf you prefer to review posts before they are published, you can enable admin approval so that you get to see the post before it goes live on your site. To enable admin approval:
