How do I merge my parent/guardian accounts used in different teams?
Parent/guardian accounts can be merged into another parent/guardian account or into a regular player account, just like your other accounts on Playerlineup.com. You can merge accounts via the top menu: select My Account → Merge accounts. The accounts to be merged must use the same email address. A link sent to that address opens a page where you choose the accounts. Only merge accounts that you alone use.
You can switch between your teams via the top menu, and you can always see the latest events from your teams here: https://playerlineup.com/users/sessions.
