You don't need to use sudo at all. I just tried it without, it worked fine. (On OpenBSD, but that shouldn't matter.) Logging doesn't have anything to do with sharing sessions, either, though it is quite useful for other stuff. The multiuser section of the manual is here (http://www.delorie.com/gnu/docs/screen/screen_25.html http://www.delorie.com/gnu/docs/screen/screen_25.html), and there are a couple commands for changing user permissions.
