Heya folks :)
The Wikidata team is excited to let you know that http://wikidata.org is now online and running the repository code \o/ You can now create items and add language links to the various Wikipedias to them. Thank you to everyone who helped. There are some caveats! We're still testing things and fixing minor bugs. Please let us know about any problems you find and go easy on the new wiki.
We're now working on phase two (infoboxes) and at the same time are working on getting the client ready for deployment on the Hungarian Wikipedia. I unfortunately can't yet give you a date for when that'll happen.)
Cheers Lydia
