Hallo,
For a while it bothered me that there's an account on Twitter called "wikisource", which didn't actually belong to project we love, and which didn't publish any tweets. So I emailed the Foundation about it and voila: It is now an official Wikisource Twitter account: https://twitter.com/wikisource .
It didn't publish anything yet, but the Foundation's communications people are probably planning something. If you have any ideas about using it to promote Wikisource, speak up!
