I want to do more in DocuSign, like send an Envelope or create a Template or PowerForm

Ask your DocuSign Department Account Administrator give you a new permission profile (role) in DocuSign.  Look up your Departmental Account Administrators for your corresponding L4 on the Active Account sheet.

If you need to find what L4 Department you're in, search your name or email address in CalGroups. Then, look up your Department Account Administrator on the Active Account sheet.
