How do I assign permissions to an Access Level for a particular group of users?
Access levels work in conjunction with groups - each group has a certain permission level for each of the access levels.
On the ‘Groups‘ page (within Admin), you will see a list of all existing groups. For each group in the list, a number of options are available. The Access Levels option will enable you to change the permissions that the group has on the access levels.
A key to the download and upload permissions is given on this page.
