eWorks and our technical consultants are using best practice to test, install patches and maintain our Moodle sites. As part of this process, there are user accounts in all sites required for this purpose.
We have experts in the areas of Alfresco, themes, Mahara, grade book, etc. Each of the accounts is used by a different user, and their changes can be tracked in Moodle’s logs if required.
These accounts are not charged.
