Before ADEC can alert you via email, you need to calculate the Kp Index you want to be alerted on for your area. You need to determine your magnetic latitude, and this will enable you to select the Kp index you're interested in.

Other points you may want to consider about Kp and viewing aurora:

If you live in a city, light pollution may be a problem, so you'll only want to be notified on really good displays, you may want to increase the Kp by a unit or two.
The Kp index does not gaurantee that when you're alerted there will be a display, but it's a pretty good approximation.
The Kp index is calulated by a neural net upto 45 minutes in advance of the event happening.
Moonlight can reduce how effectively you can view the aurora.
If the sky is overcast you won't be able to see the Aurora.
The best time to see an aurora is at local midnight. However, the higher the index, the more likely you are to see it at other times of the night.
If you're working with a Kp index that is close to the index for your location, the best direction to see the aurora is North.
The higher the Kp index is, the more likely you see the aurora in any direction including overhead.

Your email details will not be released or sold to anybody at all, you have my word. I hate spam like most people and like keeping my personal information to myself and I feel strongly on this point. The email addresses you provide will only be used for aurora alerting and information I occasionally send about the service provided.

Alert Email Address

Where do you want the aurora alerts to go to? This can also be a pager of mobile phone email address.

Info Email Address

Location where you want the updates about the service and your account to go.

Password

Password for your account. (Your alert email address is your login).

Password (Retype)

Retype your password.

Kp Index

The minimum Kp Index that you want to be alerted on. Here is a new page which will enable you to figure out your alerting Kp index for your location. www.AuroraChasers.com/GeoToMag/

Offset From UT

The number of hours you are infront of or behind Universal Time(GMT). If you are behind GMT, put in a negative number, if you are infront, a positive number. If you're not sure, you can find the UT time now.

Alerting Frequency

Once the Kp index has reached your predicted one, you will be alerted. After this you can choose two types of service. The "quiet" one will only notify you when your threshold has been exceeded, and once again when it's gone below your threshold. The "noisy" service is more designed for people who are serious about photographing aurora. It will notify you when the threshold is exceeded, and again at every 1 Kp index increase/decrease above this, this will send a lot of messages.
