Looks like this is the latest one

So 46,121 have registered at some point. Not all are active or participate though.

I just click on a users name and then backspace over the last digits and start entering numbers to find the upper range. Then narrow it down from there.

Edit:

The above was valid when I posted it now there has been one more added. I only mention this to clarify the record in my post. The one below was valid at the time of this edit but I imagine it will continue to change as new members sign up.
