A few times during the year, we send out a proposal form to our community to solicit topic and speaker nominations. Watch for those emails! We approve sessions on a rolling basis, so the earlier you're able to submit, the better your odds of being approved.
Please note that we receive a ton of submissions! While we want to be as inclusive and participatory as possible, we can't approve all of them. If your idea isn't selected for a formal session, you still have many options to participate at ND—including hosting a meetup, participating in open discussions, or connecting informally with others who share your interests.
