A live online session is almost always accompanied by a presentation using PowerPoint or Mentimeter, and you may also wish to circulate other materials with your session. Always consider accessibility and make use of accessible templates for PowerPoint and Word, which are available on the LCCOS intranet Sharepoint site.
At the start of a live online session you may want to consider having a slide to display that welcomes attendees and includes brief guidance on how to test their audio, and housekeeping for the session, such as whether we would like them to stay on mute, etc.
