Contributing is more involved than simply downloading a profile. I think you have to use the TaxiDB API: http://sourceforge.net/p/openicc/taxi/ci/master/tree/docs/api_doc.txt I you are interested then you can contact the OpenICC project to ask for details: http://www.freedesktop.org/wiki/OpenIcc/ -- Regards, Mick
