Resending an activation link to a player can be done anywhere a player is listed (aside from association). Below is an example when accessing the players profile from the team they are on.
Step 2: Select 'My Accounts' from the left hand navigation > then select 'Club Account' > select your club
Step 3: Click on 'Club Details'
Step 4: Click on 'Competitive Players'.
Step 5: Click the players name > Click 'Resend Activation Link'. This will then send them the link so that they can set up their password to have access to their player account.
