Some times adding a note to users is needed for other moderators to be familiar with events for future references.
You may wish to let your fellow moderators know why a user is flagged, or perhaps to let another moderator know that this users has prior permissions to post content that may land in a grey area and have various responses to.
After activation, a <code>Toggle user notes</code> link will be available to moderators under the author information on every post, this will expand the existing notes for a user, and provide a field for adding new notes.
When a note is added, all moderators can see the note, who added it and when. The timestamp link also provides a link to the post the note was added from to give an indication of why the note is there.

User Notes for bbPress

I've reviewed this plugin in my BuddyPress User Blog, I think it works great but should be enhanced to add an indication that the user has a note against them and also there is a need to be able to delete the note, recording the data of the note would also be useful.

Works Great!

Let moderators apply notes to individual users on your bbPress forums.
