I dug up some musics by "The Rival" off some US PC mag. AMP states, it's the same guy as "Mindless" (Netherlands).
There are two "Mindless" on AMP, and from the look of it, "The Rival" was not European
. He was sysop of an US board (SCi).
So, there's probably a good reason to have this "The Rival" set as old handle, however, I'd say it's the wrong "Mindless".
Crown, can you check this out please ? I'm afraid there's not much to go, as I can't provide a real name for The Rival. On the CD, there are but 3 musics waiting by "Mindless" and they don't bring light. I've checked all "Mindless" musics online and none refer to "The Rival". So, it's outside info only.
Note that "The Rival", according to the musics I've dug, was a member of "Nosasoft (NSS)".
