I'm involved with the Wiki Project Opera because I can't seem to leave articles on opera topics alone for very long. In doing so, I'm dropping all other subject areas from my "Watchlist" so as to focus on all things opera.
I do not suffer fools - especially vandals - gladly. Therefore, shall make my opinion of anonymous editors pretty clear on their user pages when it is clearly as a case of repeated vandalism after warnings.
Update on current projects on 15 January 2014
1. The operas of Giuseppe Verdi:
Since I have a personal ambition to see a performance of every opera which Verdi wrote, I intend to make sure that all of the articles have a proper intro paragraph, performance history, roles tables (completed), a synopsis, synopsis format (done), noted arias integrated into the synopsis, recordings tables, significant refs and support notes, properly formatted refs, etc.
So far the outstanding operas which I have yet to see are only Jérusalem (which I shall see in Sarasota, Florida in March 2014), while the other is Aroldo (no known upcoming performances....). I'm not sure that I'll count having to see Gustavo III, although I'd certainly make the effort if it were to be presented.
2. Latest priority has been to work on the operas of Rossini and Donizetti,
especially where the are performances (or concert performances) coming up. Therefore Donizetti's Belisario has been updated because was given in London in October 2012. His L'assedio di Calais was given in the UK between March and May in 10 venues; I saw it on 27 April. Now completed a big update of La donna del lago prior to London and Santa Fe peformances last Spring/Summer; working on Tancredi prior to a May performance in Paris. Donizetti's Il furioso all'isola di San Domingo was expanded prior to the October 2014 performances in Bergamo and the 2015 presentations by English Touring Opera in England.
In general, all articles on Rossini, Bellini and Donizetti articles will have full reference source sources, prior to article expansion.
I've contributed to this significantly over the last few years, since I have an ambition to see opera performances in the majority of the great European houses. I started by attended performances at the Royal Opera House, Covent Garden in London in 1958, and have been fortunate enough to have lived in (or close enough to) several great opera houses, including those in San Francisco, Chicago, and New York. Presently, I live in Santa Fe, New Mexico where there is a great summer opera festival - in a a spectacular semi-outdoor setting.
I intend to get back to the Italian houses list and flesh it out more.
4. Reformat as many opera articles as can be found using the most recent WikiProject Opera article guidelines.
