Wikipedia:JFII

JFII is an initialism for the direction Just Implement It. This instruction is sometimes given in response to a proposal when a member of the community believes that the proposal could be uncontroversially implemented without seeking consensus first. Several alternatives to this meaning exist. E.g., in response to a complaint that partially implementing a proposal did not have the desired result, someone may say, "Just Fully Implement It." After a long wait for a proposal to be put into action, someone might say, "Just Finally Implement It." JFII can also be used as an enthusiastic show of support for an idea: "Just Fantastic! Implement It!" In the words of stevesan: I bet you that if people actually implemented every great idea they had, they would realize how much they all actually suck...Having said that, the only way to realize that a great idea is actually great is to implement it. Nothing more nothing less...Yes, it'll be tough if you don't know how to do it. So learn, or get a friend to help you...Action over thought.
