what exactly is it? what makes it different from anarchism? what makes it different from communism? been searching google for hours, very confusing subject...

Anarchy: A social state in which there is no governing person or group of persons, but each individual has absolute liberty (without the implication of disorder).

Communism: a socioeconomic structure and political ideology that promotes the establishment of an egalitarian, classless, stateless society based on common ownership and control of the means of production and property in general.

In communism, a representative body of forms the government and decides on the major decisions of the state

Anarcho-communism stresses the abolition of money and the introduction of the gift economy to facilitate the exchange of goods.

In anarcho-communism, profit no longer exists. Not only that, but goods are given away as gifts in the certainty that others will also give products back (in an industrial setting, this would occur between worker syndicates as well as between individuals). If one syndicate does not share their products, they will not receive resources from other syndicates, making it in their best interest to share.

Anarcho-communism also advocates the abolition of work in the sense of wage slavery, and recommends worker self management to improve working conditions, increase efficiency, and make working enjoyable.

...Personally, I think Anarcho-communism is a paradox.

Anarchy - Overthrow of government, absence of rules.
Communism - Excess of government, everything is controlled by the state

Anarcho-communism - Nothing, cannot exist.
-OR-
Anarcho-communism - The state operates on the principle of no rules, and chaos reigns with the government at the centre of it all.
