I'm Yair Rand, administrator on English Wiktionary, Wikimedia Incubator, and Mediawiki.org, and formerly an admin on Wikidata. Mostly I work on javascript stuff. I am the author of
ReferenceTooltips (enabled by default on over 50 Wikipedias), the
SignWriting Keyboard for sign language projects, numerous English Wiktionary
gadgets and user scripts, several
Wikidata tools, a bunch of watchlist scripts (
1,
2,
3,
4), and some
otherusefulscripts on other projects. I contributed code to the
SignWriting Viewer,
Page Previews (formerly known as Hovercards, formerly known as User:Yair rand/NavPopupsRestyled.js), and
CSSJanus.
