An exception are people who you want to see a letterbox on Atlas Quest that otherwise might be restricted from seeing them for any reason.

Exceptions are specified as mailing lists. The primary purpose of mailing lists are to contact groups of people you know, but they also do double duty as whitelists and exceptions if you choose to use them in that manner. Exceptions, obviously, do not apply to anyone who is not logged into Atlas Quest.

Anyone on your exceptions will be excepted from all restrictions—including P and F-counts, group restrictions, whitelists, dependencies, and whatever other restriction options may be added in the future.

To apply an exception to your boxes, you must be the owner of the letterbox, then follow these steps:

1. Create a mailing list if you don't have one already. You'll probably want to give it a name such as "My Exceptions" or "My Friends."
2. Add everyone who should be a part of that group. A list can have any number of people including nobody at all.
3. While listing or editing a letterbox, edit the Exceptions section of the Restrictions box. If you have any mailing lists (which you should now, if you did step #1), they'll all be listed as options. Select the mailing list you created in step #1. If you need to view or edit the list, click on the name of the list and information about the list will open in a new page.
4. Save the box. You're done!

To add or remove someone from an exception, edit the mailing list that is being used for that purpose. You do not have to edit or change the box listing in any way to apply such changes.
