How do I apply as a part of an agency?

If you are an agency owner, then you should 1st signup as an expert "To Work" with the user details of the agency owner. Thereafter, you can 'Add an agency' to your account by referring to the article here (https://econolytics.zendesk.com/hc/en-us/articles/360047633514). 

Please note that if you are an employee of an agency and would like to enroll your agency to the platform, you can always ask your agency owner to do the same. However, if you want to register on the platform as a freelancer yourself, you can signup on the platform 'To Work' after due diligence of your employment contracts.
