I was trying to find statistics for the number of caches in Germany, that are registered in portal opencaching.de, a free of change and open alternative to GeoCaching.com. But I've failed to find such numbers. In polish version of OpenCaching the statistics are available under the link in the main menu. But how to find out that number for german OpenCaching? Or, if there are no such statistics presented on page, do you know at least the estimated numbers of caches registered in that portal?

Questions on The Great Outdoors Stack Exchange are expected to relate to outdoor activities within the scope defined in the FAQ. Consider editing the question or leaving comments for improvement if you believe the question can be reworded to fit within the scope. Read more about closed questions here.
The only way that you can really find this out if they don't provide the stats on the pages is to contact them.
However, in terms of a slightly different question (the rough number of geocaches in Germany in general) this website says it was approaching 200,000 August last year (2011), so I'd imagine it's still in that ballpark but may have crept up a bit.
It seams, that there is another site for statistics, which is not linked (or the linking is not obvious. The statistics for Germany can be obtained under http://cms.geocaching.de/index.php?id=9
So, OpenCaching has ~28k caches in Germany, and GeoCaching ~192k. That means that GeoCaching has over 6 times as many caches in Germany as OpenCaching (quite suprising, because in Poland it is the opposite).
