Two links for you: http://thefounderconference.com is next week and you may still be able to pitch your co-founder position there. Otherwise, http://www.meetup.com/Co-Founders-Wanted-Meetup/ runs every other month. Where are you located?
Thanks for the links. I'm in Chicago, which makes it hard to attend SV events.
