I was asked today, is there a way to see who is subscribed to your blog? The short answer is yes, if you don't mind editing your stats file. I modified my own copy, outside of what you download, so I could see my subscribers, but only if I was logged in. To add the same mod to your code, simply find stats.cfm, and add this:
<cfif isUserInRole("admin")>
<cfquery name="getpeople" datasource="#dsn#">
select * from tblblogsubscribers
</cfquery>
<cfdump var="#getpeople#">
</cfif>
It isn't pretty, but works great.
