Cryptic crosswords

A centralised store for knowledge both general and arcane about cryptic crosswords. Information regarding these is currently cast far and wide across the Internet, and it would be a good idea to have it all in one place. Content would be things such as: information about lesser-known variations of cryptic crosswords, solving guides/tutorials, links to useful websites, lists of commonly-used indicators helpful to both solvers and setters alike, a clue competition/clue of the day, biographies of setters and prominent solvers, tournament results and user-submitted crosswords (moderated).
