I don't know that, but you can look up the official financial
statements of Segelflugszene gGmbH on
https://www.ebundesanzeiger.de/ebanzwww/wexsservlet (no deep linking
possible, unfortunately). The statement of 2008 and 2007 says they
had an income of about 50.000 EUR each year.

The OLC software (or part of it) is developed by at least two
commercial software companies, namely Instant Solutions
(http://www.instantsolutions.de/referenzen_de.html) and Hosting Agency
(http://www.onlinecontest.org/olc-2.0...corganisation).

I guess this is where much of the money is spent.
