This allows your members to easily buy additional tokens without having to go through any extra steps. Before you can begin configuring Centrobill to use the Token Plus feature, you must first enable it for the sites you want to offer it on in the Sites Admin. Go to the [Sites Admin](/nats-admin/sites.md), locate the Token Sites that you want to enable this feature on, and click the "Set Join Options" action icon. Edit the join options that you want to enable Token Plus for, then check the "Token Rebuy Allowed" setting here. For more information on this process, please see our "[Token Plus](/using-nats/one-click-systems/token-plus.md)" page. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
