Addendum: Just in case Harald is not reachable: I'm available to answer questions and coordinate communicatins around KeepRight for a while until the new "project leaders" have been found.
Yours, S.

Hi,
The founder of KeepRight [1] seeks volunteers who are willing to take over maintaining the website!
KeepRight is a well-known and important quality assurance tool for OSM [2]. Many projects rely on it, like the "Quality Assurance Tools script" for JOSM [3] or the Kort Game [4].
Please contact Harald at keepright at gmx dot at if you are interested or have questions.
Yours, S. (found via german OSM forum [5])
