Also, the mood theme guide is vaguely out of date (mainly in that it includes information on submitting new mood themes); should the relevant information be included in the mood theme FAQ, with a link to the guide for more information?
Anyway, my proposed addition is the following. (Italicized lines are in the existing FAQ, and are mainly for placement and text flow purposes.)
Instructions on how to create a custom mood theme can be found at http://www.livejournal.com/doc/find/?guide=moodicons.
To edit an existing custom mood theme, you need to know the ID number of your theme. If you have forgotten the ID number, you can recover it using the Admin Console (http://www.livejournal.com/admin/console/) by executing the following command:
This will list all public mood themes, followed by any mood themes that you own.
To see which moods are defined for your mood theme, execute the following command:
You will need to replace <themeid> with the ID number of your mood theme. Do not enter the < or > symbols; these are only for reference purposes.
You can preview your mood theme at http://www.livejournal.com/moodlist.bml?moodtheme=<themeid>, again replacing <themeid> with the ID number of your mood theme.
Images used in custom mood themes must be hosted by [...]
Also, "It is not possible to delete a custom mood theme" should probably be inserted somewhere, though I'm not entirely sure whether it would be better before the remote loading paragraph, after it, or after the public mood theme paragraph.
