julian I want to develop a system that prevents university students from sharing their accounts. In other words, I want to ensure that no more than three different devices can be logged into the same account simultaneously in short, to limit the number of devices that can be logged in at the same time.

@baris Thanks so much I’ll try

@baris Yes, it makes sense — if the forum has a large audience, tagging might overload the site. But I’d like to make an announcement, maybe just one time. How can I do that? Is there another way to do it?
