What It Does
This module adopts the known (or recognised) user concept, like you see on websites like eBay and Amazon, where a user who has previously logged in to the site is remembered by a cookie. In the case of this module, the site administrator can optionally assign a role to known users, extending their permissions to do some things that are more than an anonymous user can do.
As an example, with a site I'm working on you have to login to download files. However, for "remembered" known users we don't want them to have to login just to get a file - that's annoying - so we'll create a 'known user' role, set it as the role for known users to receive (in admin/user/known-user-role) and allow it to download files. That means you don't have to login fully to download files, but you must have logged in at least once on that computer in the last 30 days.
