An existing user with access to the shared YouTube channel can allow others to work with the same ‘Brand’ channel, incl at different levels (neat!)

• Got to your channel: https://www.youtube.com/account
• This is where all ‘Brand’ channel settings can be tweaked
• Under ‘Channel managers’ choose ‘Add or remove manager(s)’; then ‘MANAGE PERMISSIONS’
• Add new person:

• Select ‘Owner’ (or as you wish); ‘invite’
