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, 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 other useful scripts on other projects. I contributed code to to the SignWriting Viewer, Page Previews (formerly known as Hovercards, formerly known as User:Yair rand/NavPopupsRestyled.js), and CSSJanus.
