A Zoom Channel gives you a permanent location in which to write messages to any member. The history can be read as it develops by those wishing to catch up, find shared links, etc. Joint video meetings can also be conducted. This facility is useful for researchers, work experience tutors and similar groups who have a lot of external contacts.

• Click on "Chat" in your Zoom Client (login is necessary):
  
• Select "CHANNELS" from the left-hand menu and click on the "+" icon:
  
• Select "Create a Channel". You can add anybody who has an e-mail address.
• You may write in shared chats or click on the camera icon (small square at the top) to hold video conversations.

NB: External participants may be permitted to enter ordinary Zoom meetings, provided that "Only authenticated users can join: Sign in to Zoom" was not selected while planning a meeting (if one or more participants are external):

NB!! If external users are unable to download Zoom Client because of their company's or organisation's policy, they may participate using the Zoom web client: https://support.zoom.us/hc/en-us/articles/214629443-Zoom-Web-Client
