Also just to elaborate... drabble is a typed response to a prompt in paragraph/story form. The ideal drabble is exactly 100 words- no more, no less.
Drawble, on the other hand, is the drawing equivalent of a drabble. A quickish drawing on response to a prompt. Naturally there's no 'line limit' as there are word limits, but everyone usually just does a sketch or a slightly cleaned/colored sketch.
IDDN means, like Moxy has said, Impromptu Drawble Drabble Night. DDN on the other hand, means Drawble Drabble Night- as in the official
planned nights. Impromptu nights are... as the name implies, impromptu, and is brought about by a certain number of members appearing in Chat all at once and having enough interest to start one up. Currently I believe there needs to be at least 18 people in Chat to start an IDDN up.
There is also another form of DDN... the
dark siiiide!! Just kidding, but really. There is another kind called the GM DDN... which means Gutter Marble Drawble Drabble Night. These are as far as I know
only planned nights and not impromptu. They take place in the GM(18+) Chat room. No one under 18 is allowed.
Also GM means Gutter Marble; anyone over 18 is classified as a GM, though there are people who choose to not be a GM by choice. (Avoiding reading/writing or lemons or smuts of any kind)
YIM on the other hand means Young Impressionable Marble. These are any users under the age of 18. They are our hatch-lings, so to speak!
