Public calendar with statistics

I manage a website for a club that has a yearly event schedule. The site is hosted with Earthlink and they have no clue about a calendar server. In the past, I used a website service to publish the calendar so folks could subscribe. That service went away and I have been using iCloud. My question is: I would like to track statistics on how many folks have subscribed. Or even who they are. Looks like iCloud doesn’t offer those options. Any recommendations?

Don’t think Google offers that either. You might consider a route within your website which captures an email prior to having access to the calendar sub.
