If you are feeling social, on Toucan, talking to people is easy.
When you click “Join the event”, you’ll be transported to the event space. If your friends are there, you’ll see them! And you’ll be able to tell who’s who by seeing everyone’s profile pictures. (Another perk of authentication)
If you hover over an individual at the event or an existing group conversation, that person/group will be enlarged. You’ll be able to see the name(s) of the person/people in that conversation, and you’ll see his/her/their profile picture(s) much better. All you have to do to join someone in conversation is click on them. And if you see that they're already in a group, clicking "Join" is your ticket into that group.
If any of it is confusing, I’ve labeled all of the buttons in the screenshot below :)
