Although Wet Ink does not support audio/video chat natively, you can easily use one of the options below and just link to it from your class.
Note: The options below are provided for informational purpose only. Wet Ink does not provide support for these options. You could also use any other tool you are familiar with.
1. Google Hangouts
You could use Google Hangouts for up to 25 participants. Notify students by posting an Announcement in your class with a link to your Google Hangout. When people click on that link they’ll be taken to the Google Hangouts chat.
Here is a nice video which shows you how to start a google hangout and invite people to it.
2. Uber conference
Uber conference is audio only but visually shows who’s talking. It is a great free option for up to 10 participants. Notify students by posting an Announcement in your class with a link to your Uber conference.
A paid option to consider is Zoom.
