Hello Ambassadors!
I wanted to give you a heads up that there is a new extension available for use on Wikimedia project wikis; Score!
http://www.mediawiki.org/wiki/Extension:Score
It was enabled yesterday during the regularly scheduled MediaWiki deployment window.
See what it can do at this English Wikipedia Help page: https://en.wikipedia.org/wiki/Help:Wiki_markup#Musical_notation
This is a long time request, first reported in August of 2004: https://bugzilla.wikimedia.org/show_bug.cgi?id=189
We'll announce this in a more wider fashion in a few days, but I wanted to give you all a heads up.
Thanks, and as always, please do let me know if you have any questions.
Greg
