Long time ago I purchased domain cswp.cz in order to use it in same
way as enwp.org
for czech wikipedia (cswp.org
was taken by something).
I think that it would be probably better if it was owned and
maintained by WMF rather than me, but I don't really know where to
ask, neither if ops are actually interested in maintaining it, the
script which redirects the page is pretty simple:
$uri = $_SERVER['PHP_SELF'];
$target = "http://cs.wikipedia.org/wiki";
header ("Location: $target"."$uri");
I can't really provide any data on usage of this domain, because I
never collected any, but if there isn't any long-term plan for global
wiki shorteners I think this domain could be used.
