-Each container in Remository has provision for setting groups that can do various things. The four options are upload, download, edit and auto-approve. You can enter as many groups as you wish. It is possible for Remository to manage the groups, but since Joomla introduced more flexible groups, it is normally more sensible to use the CMS groups. This can be selected in the "Options" for Remository. There is a pseudo-group called "Nobody" which never has any members and disables the relevant facility.

This can be selected in the "Options" for Remository. There is a pseudo-group called "Nobody" which never has any members and disables the relevant facility. It is important to use "Nobody" to block an operation - having no groups selected makes the operation available to everyone.
 The first three settings are self explanatory. Auto approve is a little more complex. What it means is that when a user uploads a file, if the user is a member of one of the groups set for auto-approve, then the file will be immediately published and available for download. If the user is not a member of any of the auto-approve groups, the uploaded file is held for approval by an administrator through the Remository admin interface.

 The Amazon naming system, like the normal disk system, does not prevent name clashes. Just as with the file system, you can guarantee to avoid them by specifying "Real with ID" as described above. If that option is turned on, then each file will be placed in its own "directory" that has a name based on the file ID.
-Using Amazon S3 gives you a lot of flexibility over storage (although you have to pay for it!). It also means that when a user downloads a file from your repository, it is sent to them directly from Amazon. That will normally be faster than sending from your web server. Again, there is a cost, but it is small unless you have a very large quantity of downloads. The use of Amazon clearly reduces the load on your web server, which may be a helpful move.
