r9k is short for robot9000. It was more or less a random board (an orange board, not blue). The notable feature (that set it apart from b) was that the 'robot' would not let you post (it would mute you) if what you said had already been said before (so you can't just post 'sage' or 'no u'.. it has to be unique. Same went for images. You had to color one pixel differently and put a muteblockrandomtextthing at the end of your post. If you tried to post a dupe, it would double your temporary ban time (so if it started at 1 minute, next you're banned for 2min, 4min, 8min, etc). It's hard to get any more specific, but it was removed in some restructuring or something. I forget.

To add to this thread, I've also lurked some other forums: Badger & Blade (mostly about shaving), Jemsite (information-rich guitar site, unlike UG, which is plagued by complete speculation by people who have never heard the equipment...), Gearslutz (music / audio recording enthusiasts), Fractal Audio Forum (they make a guitar pre-amp, an Axe-Fx, which I use), Basenotes (fragrances/colognes), and Macrumors. Can't remember any others. It's always nice to see certain users from this forum pop up in the strangest places (ie Uncle Erik).
