Can someone tell me what access this gives to authors and users? If I wanted a guess author what would they have access to?
If I remember correctly (been a while since I worked with multiple authors), they'll be able to login to the admin area but only have access to the "Write" and I believe comments moderation areas. Though, some of this may have changed too with WordPress updates over time. Why not just create a test author account for yourself and see what it lets you into?
