If you are a member of more than one fishing club that uses Clubmate, you have the ability to manage all of your accounts under the one email address.

This means you must use the SAME email address on all the profiles you across all of the Clubmate clubs you are in.

You can then switch easily between clubs and manage your memberships from one place. 

After you've logged in to Clubmate, from your members area on the right hand side click on Switch account

Here you will see all of the profiles you have listed using the same email address.

Just click on the relevant profile/club you need to switch to

Done!
