Another addendum: 
There is a SVN mirror on github: https://github.com/CloCkWeRX/keepright-mirror
We found one person who is willing to take over.
Now we need at least another one...

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.
