I had to. While others on the list have assisted me with tablety issues, you helped this country boy not only understand the basic workings of public transportation, but understand the basic workings of public transportation in German. Without your help, I'd likely still be lost somewhere in Berlin, probably having not yet even reached the Ibis.

Strangely, in real life you conspicuously lack a big, lime green "Thanks!" button, so voting for you here will have to do.
