Hello rojo and Krummhorn,
you just welcomed dirt, crud, feculence, filth, muckiness, mud, smut. This is what "Dreck" means in german. A good laugh, because he said: "Hi everyone this is dreck", which (in german) means that this all here (or himself) is "dreck". For me it seems, that people very often get a welcome without thinking. Sorry, I know, it´s not meant, but sometimes it seems so.
Hope you don´t mind
Torsten
