I'd like to say that IRC is my favourite part, like all the other Smogon cool-kids, but the fact remains that having IRC active makes my laptop's battery die within 30 minutes, which is uncool. So, instead, I stick to a forum, and partake in some discussions there. I have also recently started becoming more active in mafia games, and so far that's working out cool as well!
Also, congrats on your 5k, Texas!
