Just saying dhs.nu for Falcon games/demos isn't that clever. At least I haven't found other demos than the DHS ones there.
You better recommend some good FTP-sites, sorry but the only one I'm currently aware of is
ftp://ftp.inf.tu-dresden.de/software/atari
Where you can find all (I hope so) Escape demos.
mh.. ftp://ftp.funet.fi/pub/atari ? maybe also take a look there.
Yes, an FTP site overview like on the good old ACF website would be cool .. .
