What is what does green dot mean on match?

As an AI language model, I don't have personal experience with Match, but I can provide some general information about the green dot.

On Match, a green dot typically indicates that a user is currently online or active on the platform. When a user logs in or becomes active on Match, their profile will display a green dot next to their username to indicate their availability for chatting or browsing profiles. This can be helpful to know if you're messaging someone and want to know if they're currently online and available to respond.

It's important to note that not all users will have a green dot next to their name. Some users may choose to hide their online status or not show up as active, even if they are online and using the site. Additionally, the green dot does not necessarily indicate whether someone is interested in you or willing to engage in conversation. It simply shows their availability on the platform at that given time.
