Edit members in bulk

When you click the edit members button on the clipboard, you can edit the access, groups and privileges of all of the selected members at the same time. This page is very similar to the individual edit pages, with some differences. On this page to start with, there are NO settings. Any areas you leave unset will not be applied to the members. This means that you can select one thing to change and apply just that. All others will be ignored.
