NANOG67 Attendees, Welcome to NANOG 67 in Chicago ! The Program Committee has begun accepting Lightning Talk submissions for 10-minute speaking slots on Tuesday and Wednesday afternoon. A lightning talk is a very short presentation or speech by any attendee on any topic relevant to the NANOG audience. These are limited to ten minutes; this will be strictly enforced. If you have a topic that's timely, interesting, we encourage you to consider presenting it. Please submit an abstract via pc.nanog.org <http://pc.nanog.org/>, and you'll be notified the night before if you've been selected. Thanks!
