When I was using Ibill I used a Member Admin script called MMS from
http://www.primeinternet.net/mms-tou...nt-control.htm and it worked great. It checks for expired users several times per day and has conf settings for custom e-mails and all. I have had it for two years now and its rock solid. Even with all the pincode fuckups at Ibill and the weekly system changes this program never failed.
