Notes

The Notes feature was released with the Mobilising Armies update of 8 July 2009. It is a part of the interface that allows players to add up to 30 notes in plain text, with a maximum of 50 characters each, for a total of 1500 characters. Players can add a note by pressing the button at the top-left of the interface, which is marked with a green 'plus' (+) symbol, and then typing on the keyboard.

Players can customise an individual note by right-clicking it. This allows them to change the colour of the note's text to any of four different colours — red, green, amber, white — with white being the default. They can also edit the text of any note, using the Caret to select certain parts of the note to go back to.

Players can delete any note by selecting it and then pressing the "Delete" bar, or delete all notes by right-clicking the Delete bar and selecting "Delete all".

The Notes feature is useful for keeping track of prices or writing down lists of things to buy. It could also be used in quests that require you to remember a word or phrase.

The code for player notes was optimised on 9 November 2009.

Players who are under 13 years old cannot use this feature. This feature can also be used on Quick Chat worlds.

Easter Eggs
Typing any key or specific phrases will result in the note changing to a popular cultural reference or meme.

Mod Hope has tentatively confirmed there are more to be found.

Trivia

 * When the game state is rolled back as a part of a bug fix (as happened on 14 April 2010), notes that were added in the period that was rolled back are not deleted. For example during the time to be rollback, a player could have finished a slayer task, got a new one, and made a note about it. After the rollback, the note still exists for the new task, even though the player is now back on the previous task. This retention of notes, however, is possibly not a glitch, since the player could have made a note that would be unaffected by the rollback.
