Hi Basildane,
Sorry youâre annoyed by this notification! We luckily donât have the email addresses of all our users, nor do we know their server address, that would be quite a privacy violation 
so we wonât be doing that. You can of course sign up to our newsletter if you like.
Where this notification comes from
Your server has an app, the âNextcloud announcementsâ app, with this description:
âNextcloud announcements brings the latest news of Nextcloud into your notificationsâ
This is a âpullâ process, the app looks for a feed on our servers, we donât send anything as we donât have or keep any server data.
You can configure this app in your server settings, by default it sends these notifications to the admin group, not to users. As server notifications get sent to the clients, if you use one, it can then pop up on the desktop client or the mobile clients.
If you donât want the notifications, you can disable the app or change the group of people who gets it.
You can find some more info in this github ticket: "Nextcloud announcement" - How to get rid of the conference news · Issue #426 · nextcloud/notifications · GitHub
Why oh why
Sorry if this was an annoying notification! We often get the feedback that people didnât know our yearly conference exists or when it took place, that is why we send this message this year.
So it seems the vast majority of our ~250.000 server administrators probably donât know about the conference (after all, it sure doesnât attract 200.000 visitors). For many it would be an interesting and useful event so hopefully this was a useful notification for most of them. Of course, our goal is not to bother or disturb people, I hope a yearly message isnât too much.
We recently blogged about our mission and prinicipals at The Nextcloud mission and principles - Nextcloud - your feedback is of course welcome!
