Valfarly chanced upon wikipedia and thought "that'll never work"... but after using it a few times, he eventually got sufficently annoyed by a typo to do something about it and on 15th March 2004 hit edit. From there it was a slippery slope to writing articles for things he found no-one else had written about and adding tidbits, factoids and other nuggets of information to previously covered topics. Finds himself correcting spelling and grammar far too often!
The MediaWiki software that runs Wikipedia is under constant development. Do you want to see the latest, greatest features? Then head over to test.wikipedia.org, where the development branch is tested. But be careful. That wiki runs in debugging mode, so even the smallest problem in the code might cause it to spew out error messages. Take a look at the list of features under development in the MediaWiki roadmap. MediaWiki already is one of the most feature-rich wiki engines; see the MediaWiki feature list. MediaWiki and its dependencies are open source, so if you are the inquisitive type, please take a look at the code and help improve it.
Arthur Sullivan (1842–1900) was an English composer best known for his operatic collaborations with the dramatist W. S. Gilbert. Among his early works were a ballet, a symphony, a cello concerto and a one-act comic opera, Cox and Box, which is still widely performed. He wrote his first opera with Gilbert, Thespis, in 1871. The impresario Richard D'Oyly Carte engaged Gilbert and Sullivan to create a one-act piece, Trial by Jury, in 1875. Its box-office success led the partners to collaborate on twelve full-length comic operas, known as the Savoy operas, including H.M.S. Pinafore, The Pirates of Penzance and The Mikado. Sullivan's only grand opera, Ivanhoe, though initially successful in 1891, has rarely been revived. His works include twenty-four operas, eleven major orchestral works, ten choral works and oratorios, two ballets, incidental music to several plays, and numerous church pieces, songs, and piano and chamber pieces. His hymns and songs include "Onward, Christian Soldiers" and "The Lost Chord". This carte de visite of Sullivan was taken around 1870 by the English photographer H. J. Whitlock.Photograph credit: H.
