This is a really helpful feature for artists who offer commissions, to see the most active times of day! I'd love to see it on FN as well!
Nice idea, but a simple number telling you how many users are currently online won't do the job. To find the most active times of a day, you'd need some kind of graph.
I could imagine something like this to be included in the site stats, once they go live: https://support.furrynetwork.com/topics/40-site-stats/
