Here's what to expect the first time you're invited to an Evercast room
1) When you receive an invite from Evercast, if Chrome isn't your default browser, copy and paste the invite token link in to Chrome.
2) If it's your first time using Evercast, you will be asked to create a display name and a password. The password strength meter must show at least 'Good' before you can continue.
3) You will then be asked by Chrome to "Allow" your webcam and mic. Click "Allow twice." You should see yourself and when you talk, the audio meter (bottom right) should move. If all looks good, click the "Go Live" button at the bottom.
