I will re-open it once I have time to finish automating the notifier service creation... currently there are some steps I have to perform manually each time someone registers and requests a new notifier service.
Feel free to comment here or email me if you have a great need for this notifier service... I'll set some up on a case by case basis. I just can't handle the looky-loo traffic - I have to assume everyone that registers will use the notifier when in reality only about 30% of registered users actually fill out their notifier settings page and start using it.
Thanks - who knows, maybe Google will release an update to their calendar and this service won't be needed anymore!
