Final answer:
The eLicense portal does not facilitate signing up for the PSI exam, which is usually done through specific testing services.
Step-by-step explanation:
The eLicense portal is typically used by professionals to manage various aspects of their licensing requirements. Among the options available, you can usually add a client trust account, change your address, and reactivate your license. However, signing up for the PSI exam is not typically a function of the eLicense portal. The PSI exam is a professional examination for various credentials and its registration is often handled through the specific testing organization's website or a designated testing services provider.
