The access authorisation process workflow is a built-in feature of Lookatme™.
You can have this automated to an extent that matches your business rules.
For example some or all users can be given access to immediate downloads. Alternatively you can identify particular users who will be required to have each request approved before they can download.
All the access requests and approval requests are handled elegantly within the solution with appropriate onscreen messages and email notifications to keep users informed of the steps involved.
