Frequently asked questions

What equipment do I need?

All you need to participate is a computer or tablet and connection to the Internet. You will also need speakers or headphones and a microphone. While having a camera makes interactions with the other girls and instructors more lively, it is not strictly required.

What to do if it says 'not authorized' when following the link?

This seems to happen if the Google account logged in when joining the meeting link is restricted (e.g. a school account or company policy). The easiest way is to use an incognito window or inPrivate window in your browser and follow the meeting link.

What software are you using?

Check out our new instructions video.

We use Google Meet (formerly Google Hangouts) for our meetings. You can join from a web browser using the link we email out before the class. Some of the activities work best using Google Chrome as browser. You can also participate from a tablet or phone using the Google Hangout App, however some of the online activities might not work on these devices. Of course you can use a phone or tablet to sign into the class and a computer to do the online activities.

Below is a schematic of what you will see. It is important that you mute yourself when not talking to avoid audio feedback (or in other words loud noises). Don;t forget to un-mute yourself when speaking 😎

I cannot hear anyone, what do I do?

Make sure your volume is turned up. If you still cannot hear, you might need to select the correct speakers in Google Meet under Settings as shown on the schematic below.

Nobody can hear me, what do I do?

First make sure you are not muted. If people still cannot hear you, you might need to select the correct microphone input in Google Meet under Settings as shown on the schematic above.

How do I ask questions or get help?

Use the chat feature (see screenshot above) and ask your question. One of the volunteers will respond. In case of trouble shooting, they may ask you so speak with them and/or share your screen. Beware that if you share your full screen, everyone in the session can see it.

The audio is really bad, what do I do?

Try turning captions on to see a written transcript of the conversation (look for the button next to present now). While the text is not always accurate and sometimes even funny, it helps following along. If Internet bandwidth is the issue, disabling your video might help.
