CMS: multiple users

Is it possible for us to have multiple profiles when using the dashboard?We have more than one person working on setting up the site and it would be handy for each person to have their own login.Moreover, we also use additional personnel to assist with content management and we would rather that they did not have full access to change everything about our site. Is there any mechanism by which we could restrict what changes they can make via the CMS?
