To specify who can post links in the chat, go to your chat dashboard and click Settings > Permissions, then scroll to the Post Links section.
You will have the following options:
- Anyone: Any user can post links.
- Signed-In Users Only: Only users logged in with Chatroll, Facebook, Twitter or SSO can post links. Users logged in as Guests are not permitted.
- Moderators Only: Only administrators and moderators of the chat can post links.
If a user who does not have link posting permission tries to post a link, it will be blocked in real-time.
