contacting me

Due to the insane amount of incoming SPAM I use mail filtering. I use a three stage scheme: valid-looking (inbox), may-be-spam (first spam folder) and likely-spam (automatically discarded). I do check the mail in the spam folder, but the chance of missing a valid mail there is quite high.

Kindly refrain from inviting me into "social" or "professional" networks, I hate that stuff.

A last cite about my pages:
Auf Deiner Homepage war ich auch schon. Langweilst Du Dich eigentlich sehr? Ich kann mir nichts anderes vorstellen, denn wer soviel Geduld aufbringt eine solche Schwachsinnspage zu erschaffen muß sich einfach langweilen.
Gruß, Petra
