Good news! We released WikiTrust 4.0. This version has many enhancements. The major one is that it computes various quality indicators for revisions, so that given a page, it should be possible to select a recent revision that has a high probability of not being vandalized, or unstable (in the middle of a series of fast changes).
The bad news is that the addition of these quality indicators required a change in the database content.
If you have a WikiTrust installation, you will need to re-process the wiki.
And we also need to reprocess the wiki! Thus, our demos are momentarily down.
We are currently working on bringing back up the French Wikipedia (a couple of days) and the German one (one week from now? We start once the French is up). Others will follow. We apologize for the inconvenience, and we thank you for your patience.
