Welcome to the 4.5 Trillion Project. To add collections you will need to be linked to one or more Organisations. If your organisation already exists you can connect to it by editing your profile. If it does not exist you will need to add a new organisation.
Once you have connected to an organisation you can start adding collections by browsing to the organisation page and clicking on 'Add Collection'.
Your account details including your name, email address and password can be updated under Preferences. Note that if you do not provide a valid email address you may not be able to reset your password.
