Indeed, Argus. I seem rather active. But I'm afraid it might go up and down a bit over time. Still, I try to add to a great concept and help out where possible.
I'll check for the naming of German roads as much as possible while I'm at it, but also the type of roads. As far as I've understood, it should be along the lines:
B (Bundesstraße) - Major Highway (e.g. B8 - Weseler Landstraße)
L (Landesstraße) - Minor Highway (e.g. L468 - Bahnhofstraße)
K (Kreisstraße) - Primary Street (e.g. K7 - Deichstraße)
I'll see what I can do, but for now, I'm focussing on the area near Bocholt as it seems to be in dire need of some maintenance...
