How to give a user the rights to "clear cache" I need to give a user the ability to "clear cache" since he sometimes does some changes to the menus, etc...  How can I give him a right to do that, or can I just send him a URL or post something on his admin toolbar?  With the roles and rights I've given him so far he can only go to one thing on the Configuration page and that's "URL aliases."  I recall that I used to have a way to accomplish this for the authenticated users with a little block at the bottom of the footer, but I can't find it or remember how I did it.. 

Help please, and thanks in advance.
