Finally, we have created a wiki page for exchanging offers and needs for shared rides. Please add a note if you are looking for a ride to FrOSCon or from FrOSCon back home, or if you can offer a seat in your car. Or perhaps you are looking for someone you can share a train ride with? Don't hesitate and add a note to the wiki page. Offers and needs influence each other.
The edit password for the wiki page is 'tux'.
PS: Unfortunately the wiki page is in German language only at the moment. But it should be more or less self-explanatory. Sorry for that.
