I probably have 100gig of GTR2 stuff - cars, mods, tracks, sounds, etc. - dating back to the last days of RSC, but am loathe to upload anything because of that old bugaboo, permissions. I do not claim authorship of any of this (beyond some sounds and skins, and a few tweaked physics) but can guarantee if I upload a mod or a track someone is bound to scream "Did you get permission!?" This would not be an issue except I daresay that in the majority of cases these mods, if they ever included contact information, that information is outdated (I have old files out there with Compuserve addresses, lol).
So most likely everything from nog rip is still around, just in the hands of people like me. It would be nice to have a single repository where we could make it all available again.
(Whether Nogrip vanished "for good" is unknown. The original founder sold it to a Hungarian holding company, whose business was apparently buying popular sites and flooding them with marketing to generate revenue. After several years Nogrip must not have been profitable enough so they pulled the plug on it; whether it still exists, buried on a drive, or whether it was deleted is not known. The sad part is its internet valuation around the time it disappeared was a mere $16k; on another forum several people expressed interest in buying it just to archive the forums and libraries, but emails to the holding company elicited no response ...either they are not interested in selling it or it no longer exists.)
