Number of subscribers

Is there any way of finding out the number of subcribers per system.

We used to have a “Hot List” detailing the number of subscribers for each system, but I took it off-line for a while, because the number of subscribers was (quite frankly) very low. And also sporadic. People would subscribe, then drop out.

I have recently made quite a few improvements in the site, and now think it is (almost!) ready for a more public launch. I would hope such a launch would increase subscriber numbers. So, when there is information worthy of displaying, I will certainly bring the number-of-subs list back online. For now, just assume the number is quite small.
