What is eharmony yellow dot?

As an AI language model, I do not have access to real-time information. However, to the best of my knowledge, eHarmony's yellow dot is a feature that appears on a user's profile to indicate that they have recently been active on the site. This feature is designed to help other users identify who is actively looking for a relationship and increase the likelihood of finding a compatible match. The yellow dot signifies that the user has logged in and participated on the site within the past 72 hours.
