Just spitballin' here, building off of elsons idea...
If OCN were to donate their awesome lanyards with the carabiner, I would donate some wicked awesome laser cut and etched name badges for the 125 attendees. Plus after the event, the attendees would have a lanyard!
Not sure how many lanyards OCN even has left, or how much they cost OCN in the first place, but thought I'd post up my idea -- It might be too big of a donation for OCN to swing.
so what do you say, admin? Is it something you and the organizers would consider?
