Adding a domain/website to Jollow requires selecting applicable settings. The "Unique Identifier" setting is an important option if your website allows for visitors to login or creating an account. 

Jollow can track a lot of different activities if this is the case, but it must be clearly defined in the Unique Identifier option when choosing your domain settings. 

Some examples of an Identifier:

1. Username
2. Email Address
3. Member ID

It's important that this be unique, unlike first or last name.

Additionally the Identifier must be a detail which your website members can see. When they login to your website, can they find out this detail? For example, if the Unique Identifier is "Member ID" then your members must have access to see their unique Member ID.

Where does this come in to play at Jollow?

When Participants 'Take' a Challenge they will, if applicable, be asked to input their Member ID (using the above example) from your website. Once they do so, they will have their activity tracked any time they participate in a Challenge involving your website.
