I am Kip, the current maintainer of OmegaWiki and the related MediaWiki extension WikiLexicalData. Before OmegaWiki took so much of my time, I was bureaucrat at the French Wiktionary and sysop at the English Wiktionary. I am also sysop at the French Wikisource. I joined the Wikimedia movement somewhere in 2004 I think, when the French Wiktionary was launched.
I am sometimes on IRC : Kipcool on #wiktionary, #omegawiki, #wiktionary-fr.
There is a proposal, at "OmegaWiki", to have OmegaWiki supported by Wikimedia. This would be awesome. If you believe this would be good, you can indicate your interest.
