Huh. I could've sworn I posted in this thread way back in the day, but apparently I never did.
Welp, I voted "Been here forever" on the poll because that's most true now, but I originally found GN through a recommendation that La Petit Mort/Cielmort posted in my own podcast's forum. Said post is still alive by some miracle: http://animeutahime.proboards.com/thread/2/geeknights
[CUT TO TEN YEARS LATER HAVING LISTENED TO ALMOST EVERY SINGLE EPISODE]
Aheh... Well that didn't go as planned.
(Also, I knew there was a gap between when I first started listening and when I joined the forum, but I forgot it was a full year! I believe the episode Mort first showed me was "How to Not Suck at Talking".)
