Good for game-makers, Can use indicator to see if it is good time to make a large diplomacy game or a short one. Just a rough idea that came to my head in the last few minutes.

Would be easy to implement. Just the number of profiles that were Last Seen: less than 15 minutes ago. Wouldn't be exact (though I don't think anything would) but would be a good rough estimate.

Only problem is it could be beneficial or detrimental for the community to see the actual numbers.

And to change "Last seen: 15 minutes ago" for players currently online to... ---> "Currently Online"

I strongly support both suggestions. :)

it wouldn't give any acurate number either because some players only play multi-day games and you would be counting them

Some days I only sign-in to take my turn in multi-day games, then I quit. I oppose this suggestion.
