Most of the time, you'll automatically be added to all the channels that relate to your child. So, if you have a child in year 3, you'll already be following the school channel plus the year 3 channel.
But if your school has created a new channel and then asked you to join it - perhaps for a school trip or after-school club - here's how:
Tap SchoolsThis handy little button is where you'll find everything that relates to the school, from contact details to your child's attendance - including a list of the channels available.
Tap School Page or just tap on the school's logo
Tap the All Channels button to see a list like this one below:
Simply select the new channel you'd like to join, and tap 'Save Changes'.
New posts in that channel will be delivered to your Hub feed, and if you'd like to view historical posts, just tap P > My Channels, then tap the channel name you want to view.
