@OSCo Hey there 👋🏻 I'm a little confused, what you want to tell us by the message on the registration page. Which one is "the last edition”? Is registration for 2026 already closed?
Show threadOpen Security ConferenceFeb 28
@tisba Great feedback, thanks for taking time to share and ask! 🙏🏻 We'll definitely improve this formulation. We meant to refer to last year's edition, aka 2025. Registration for #osco26 is planned to open in July 2026, we'll announce it in time here. Hope to see you there! [lisi]

@OSCo yeah, adding the year might be nice 😅

One more question: Is there some kind of newsletter or something else to get notified when registration will open? I'm not quite reading the entire Mastodon timeline and worried that I'll miss the announcement 🫣

@tisba As of now, there's no osco newsletter. In our first year, we had offered a pre-registration mailing list to inform people when the registration opens; we'll take this feedback with us to see if we want to re-introduce this option. Also, we are considering offering a community platform in the future where such announcements would be done as well. Yet for now we only have our website and our social platforms to keep folks up to date. We're on Mastodon, LinkedIn and Bluesky, if any of those others might fit your needs better. [lisi]

The missing year should now be fixed on the website 😁
