I receive a friendly answer, and in October a meeting between HaCon, someone from the "Deutsche Bahn AG" (the German rail operator) and some compunting centre people takes place - without tangible results. Meetings!
I assume the post of "WWW admin" for the HaCon service, answering all the user questions (and flames).
An automatic answering script takes care of the mail address firstname.lastname@example.org, and I am trying to eliminate the RailServer from all the search engines and hotlists. I get a lot of eMail thanking me for the service.
Melancholy creeps up inside me, but I keep saying to myself that the RailServer has done its duty and that the small number of queries in the past weeks really doesn't justify the work of keeping it alive.
