at first, thanks for your replies. Jürgen, i seriously like your long distance cycling route, http://www.heinztomato.de/wiki/pmwiki/index.php (Olafs link) And Dirk, yes there is a lot of info in google groups. Hanno, thanks for the great wiki link, it is a bit more like i mean, http://wiki.HPV.at/Hauptseite where you find some overview, and run by the people. one site i like a lot is; http://www.treehugger.com/ i like their appealing design, categorisation, interact, take action. what i don't see though is a category for HPV. also the "interact section" misses member forum/community or something, and the "take action" part i would categorise like the "get informed" heck, i am going to write them about it. python should be part of a HPV section there, don't you think? one background to my question of a categorised eco platform, with member interaction on different projects (python eg.) is that right now i am helping somebody to setup an Internet community. Thanks everyone, Dirk Jan
